Answer:

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

Explanation:

From Heat Transfer we determine that heat transfer rate due to electromagnetic radiation (\(\dot Q\)), measured in BTU per hour, is represented by this formula:

\(\dot Q = \epsilon\cdot A\cdot \sigma \cdot (T_{s}^{4}-T_{b}^{4})\) (1)

Where:

\(\epsilon\) - Emissivity, dimensionless.

\(A\) - Surface area of the student, measured in square feet.

\(\sigma\) - Stefan-Boltzmann constant, measured in BTU per hour-square feet-quartic Rankine.

\(T_{s}\) - Temperature of the student, measured in Rankine.

\(T_{b}\) - Temperature of the bus, measured in Rankine.

If we know that \(\epsilon = 0.90\), \(A = 16.188\,ft^{2}\), \(\sigma = 1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}}\), \(T_{s} = 554.07\,R\) and \(T_{b} = 527.67\,R\), then the heat transfer rate due to electromagnetic radiation is:

\(\dot Q = (0.90)\cdot (16.188\,ft^{2})\cdot \left(1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}} \right)\cdot [(554.07\,R)^{4}-(527.67\,R)^{4}]\)

\(\dot Q = 417.492\,\frac{BTU}{h}\)

Under the consideration of steady heat transfer we find that the net energy transfer from the student's body during the 20 min-ride to school is:

\(Q = \dot Q \cdot \Delta t\) (2)

Where \(\Delta t\) is the heat transfer time, measured in hours.

If we know that \(\dot Q = 417.492\,\frac{BTU}{h}\) and \(\Delta t = \frac{1}{3}\,h\), then the net energy transfer is:

\(Q = \left(417.492\,\frac{BTU}{h} \right)\cdot \left(\frac{1}{3}\,h \right)\)

\(Q = 139.164\,BTU\)

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

Answer:

the minimum volume flow rate needed to tip the block is 2.66 × 10⁻⁴ m/s

Explanation:

Given that;

diameter of the jet d = 10 mm

weight W = 6 N

Now we say

Fₓ Lfₓ - Wlw= 0

horizontal force

Fₓ = W (lw/lfₓ)

Fₓ = 6 ( 0.015/2)

Fₓ = 0.9 N

X-component of momentum

v₁p(-v₁)A₁ = - Fₓ

pA₁v₁² = Fₓ

v₁² = Fₓ / pA₁

v₁ = √( Fₓ / pA₁ )

WE SUBSTITUTE

v₁ = √ ( 0.9 / ((999)(π/4)(0.01))²

v₁ = 3.39 m/s

Now Discharge Q = A₁v₁

Q = π/4 (0.01)² (3.39)

Q = 2.66 × 10⁻⁴ m/s

therefore the minimum volume flow rate needed to tip the block is 2.66 × 10⁻⁴ m/s

The torque M which must be applied to the crank at O when the crank angle = 30° is 0.5 Nm.

Taking moments about O, the torque is given byτ = (AB x BC) sin(θ) x a

Here θ is the angle between AB and the horizontal and a is the tangential acceleration of B.θ is 180° - 2α and sin(θ) = sin(2α), where α is the angle between the coupler and AB.

Angle α is given byα = cos⁻¹((BC² - AC² - AB²) / (-2AC x AB))

The tangential acceleration of B is given by

a = (BC x AB x ω²) / (2 x BD)

where BD is the perpendicular distance from O to AB.

Calculating angle α

α = cos⁻¹((BC² - AC² - AB²) / (-2AC x AB))

α = cos⁻¹((1.5² - 0.8² - 0.9²) / (-2x0.8x0.9))

α = cos⁻¹(-0.263)α = 104.33°

Calculating θ

θ = 180° - 2α

θ = 180° - 2(104.33°)

θ = - 16.67°

We can take sinθ = sin(-16.67°) = -0.29.

Using τ = (AB x BC) sin(θ) x aτ = (0.9 x 1.5) x -0.29 x ((1.5 x 0.9 x 2π / 60)² / 2 x 0.8)τ = - 0.5 Nm

The oil is non-edible and can be extracted from castor seeds from the castor plant belonging to the family Euphorbiaceae. The oil is a mixture of saturated and unsaturated fatty acid esters linked to a glycerol. The presence of hydroxyl group, a double bond, carboxylic group and a long chain hydrocarbon in ricinoleic acid (a major component of the oil), offer several possibilities of transforming it into variety of materials. The oil is thus a potential alternative to petroleum-based starting chemicals for the production of materials with variety of properties. Despite this huge potential, very little has recently been reviewed on the use of castor oil as a bio-resource in the production of functional materials. This review therefore highlights the potential of castor oil in the production of these diverse materials with their projected global market potential. The review gives the background information of castor oil and its geographical availability, the properties and its uses as bio-based resource for synthesis of various materials. The review further highlights on the use of castor oil or ricinoleic acid as a green capping agent in the synthesis of nanomaterials.

Answer:

\(250\ \text{lbm/min}\)

\(625\ \text{ft/min}\)

Explanation:

\(A_1\) = Area of section 1 = \(10\ \text{ft}^2\)

\(V_1\) = Velocity of water at section 1 = 100 ft/min

\(v_1\) = Specific volume at section 1 = \(4\ \text{ft}^3/\text{lbm}\)

\(\rho\) = Density of fluid = \(0.2\ \text{lb/ft}^3\)

\(A_2\) = Area of section 2 = \(2\ \text{ft}^2\)

Mass flow rate is given by

\(m=\rho A_1V_1=\dfrac{A_1V_1}{v_1}\\\Rightarrow m=\dfrac{10\times 100}{4}\\\Rightarrow m=250\ \text{lbm/min}\)

The mass flow rate through the pipe is \(250\ \text{lbm/min}\)

As the mass flowing through the pipe is conserved we know that the mass flow rate at section 2 will be the same as section 1

\(m=\rho A_2V_2\\\Rightarrow V_2=\dfrac{m}{\rho A_2}\\\Rightarrow V_2=\dfrac{250}{0.2\times 2}\\\Rightarrow V_2=625\ \text{ft/min}\)

The speed at section 2 is \(625\ \text{ft/min}\).

(a) The mass flow rate will be "250 lbm/min".

(b) At section 2, the speed will be "625 ft/min".

According to the question,

Section 1 area, A₁ = 10 ft²

Section 2 area, A₂ = 2 ft²

Water's velocity, V₁ = 100 ft/min

Volume at section 1, v₁ = 4 ft³/lbm

(a) We know the formula,

Mass flow rate, m = ρA₁V₁

                              = \(\frac{A_1 V_1}{v_1}\)

By substituting the values,

                              = \(\frac{10\times 100}{4}\)

                              = \(\frac{1000}{4}\)

                              = 250 lbm/min

(2) The speed will be:

→ m = ρA₂V₂

or,

  V₂ = \(\frac{m}{\rho A_2}\)

By substituting the values,

       = \(\frac{250}{0.2\times 2}\)

       = \(\frac{200}{0.4}\)

       = 625 ft/min

Find:

Answer:

\(\eta_{turbine} = 0.603 = 60.3\%\)

Explanation:

First, we will find actual properties at given inlet and outlet states by the use of steam tables:

AT INLET:

At 4MPa and 350°C, from the superheated table:

h₁ = 3093.3 KJ/kg

s₁ = 6.5843 KJ/kg.K

AT OUTLET:

At P₂ = 125 KPa and steam is saturated in  vapor state:

h₂ = \(h_{g\ at\ 125KPa}\) = 2684.9 KJ/kg

Now, for the isentropic enthalpy, we have:

P₂ = 125 KPa and s₂ = s₁ = 6.5843 KJ/kg.K

Since s₂ is less than \(s_g\) and greater than \(s_f\) at 125 KPa. Therefore, the steam is in a saturated mixture state. So:

\(x = \frac{s_2-s_f}{s_{fg}} \\\\x = \frac{6.5843\ KJ/kg.K - 1.3741\ KJ/kg.K}{5.91\ KJ/kg.K}\\\\x = 0.88\)

Now, we will find \(h_{2s}\)(enthalpy at the outlet for the isentropic process):

\(h_{2s} = h_{f\ at\ 125KPa}+xh_{fg\ at\ 125KPa}\\\\h_{2s} = 444.36\ KJ/kg + (0.88)(2240.6\ KJ/kg)\\h_{2s} = 2416.088\ KJ/kg\)

Now, the isentropic efficiency of the turbine can be given as follows:

\(\eta_{turbine} = \frac{h_1-h_2}{h_1-h_{2s}}\\\\\eta_{turbine} = \frac{3093.3\ KJ/kg-2684.9\ KJ/kg}{3093.3\ KJ/kg-2416.088\ KJ/kg}\\\\\eta_{turbine} = \frac{408.4\ KJ/kg}{677.212\ KJ/kg}\\\\\eta_{turbine} = 0.603 = 60.3\%\)

The Bourdon tube is sensitive to changes in pressure and serves as a reliable method for pressure measurement in various applications across industries.

The Bourdon tube is a mechanical device used to measure pressure. It consists of a curved, hollow metal tube that tends to straighten when subjected to internal pressure. This change in shape is the basis for its operation as a pressure measurement tool.

The Bourdon tube is typically connected to the system or process whose pressure needs to be measured. As the pressure within the system increases or decreases, the Bourdon tube responds by either straightening or curving further. This motion is then translated into a corresponding reading on a pressure gauge or other measurement device.

It is important to note that the Bourdon tube is specifically designed to detect changes in pressure and not other variables such as temperature, voltage, or current. While other types of sensors or devices may be used for measuring these other quantities, the Bourdon tube is primarily used for pressure measurement due to its mechanical properties and responsiveness to pressure changes.

In summary, the Bourdon tube is sensitive to changes in pressure and serves as a reliable method for pressure measurement in various applications across industries.

The transfer function is a mathematical representation of the relationship between the input and the output of a system. The steady-state error, or ess, is the difference between the desired output and the actual output when the system reaches a steady state. The natural frequency is the frequency of the system's response without any external forces.

Transfer Function: Transfer Function is used in signal processing, control engineering, and other disciplines that deal with systems or signals. The ratio of output to input in Laplace transform is known as the transfer function.

Steady-State Error: The error that happens when the system is at a stable state is referred to as a steady-state error. The difference between the desired and actual response is known as steady-state error. A system's ability to track a specific input as time progresses is characterized by this kind of error. If the input signal is a unit step, then the steady-state error is referred to as the static error coefficient. The coefficient of the steady-state error is frequently used to classify systems in control engineering.

Natural Frequency: Natural frequency is a term used in physics to describe how quickly an object vibrates when it is set in motion. The number of oscillations made by a system in a given time period without any external force acting on it is referred to as its natural frequency.

The problem requires us to calculate the maximum contact pressure and the maximum shear stress experienced by either gear given the load of 40 lbf, face width of 0.75 in, and instantaneous radii at the contact point of interest of 0.47 in and 0.62 in. Let's solve for each value one by one.

First, let's determine the maximum contact pressure (pmax) using the formula:

pmax = (2F)/(πbL)

Where F is the load transmitted, b is the face width, and L is the base pitch. The base pitch can be calculated using the formula:

L = (π/2) * (r1 + r2)

Where r1 and r2 are the instantaneous radii at the contact point of interest. Substituting the given values, we get:

L = (π/2) * (0.47 + 0.62) = 0.997 in

Now we can substitute the values for F, b, and L into the formula for pmax:

pmax = (2 × 40)/(π × 0.75 × 0.997) = 85.7 psi

Therefore, the maximum contact pressure experienced by either gear is 85.7 psi.

Next, let's calculate the maximum shear stress (τmax) using the formula:

τmax = (4F)/(πd^2L)

Where d is the pitch diameter, which can be given by d = (r1 + r2)/2. Substituting the given values, we get:

d = (0.47 + 0.62)/2 = 0.545 in

Now we can substitute the values for F, d, and L into the formula for τmax:

τmax = (4 × 40)/(π × 0.545^2 × 0.997) = 346 psi

Therefore, the maximum shear stress experienced by either gear is 346 psi.

In summary, the maximum contact pressure experienced by either gear is 85.7 psi and the maximum shear stress experienced by either gear is 346 psi.
