Answers

Answer 1

The interior volume of the container is 0.0423 ft^3, which corresponds to answer choice (a).

The specific weight of the fluid in the container is 2950 lbf/ft^3, which corresponds to answer choice (a).

Let's start with problem 55.

The weight of the filled container is 127lbf, and the weight of the empty container is 2.00lbf. Therefore, the weight of the fluid in the container is:

127 lbf - 2.00 lbf = 125 lbf

We know that the density of the fluid is 91.7lbm/ft3. To find the volume of the fluid, we can use the formula:

density = mass / volume

Solving for volume, we get:

volume = mass / density

The mass of the fluid can be found using its density and the weight of the fluid:

mass = weight / gravitational acceleration

mass = 125 lbf / (32.2 ft/s^2)

mass = 3.88 lbm

Now we can find the volume of the fluid:

volume = mass / density

volume = 3.88 lbm / 91.7 lbm/ft^3

volume = 0.0423 ft^3

Therefore, the interior volume of the container is 0.0423 ft^3, which corresponds to answer choice (a).

Moving on to problem 56, the specific weight of a fluid is defined as the weight per unit volume of the fluid. We can find it using the formula:

specific weight = weight / volume

We already know the weight of the fluid (125 lbf) and its volume (0.0423 ft^3), so we can plug these values into the formula:

specific weight = 125 lbf / 0.0423 ft^3

specific weight = 2950 lbf/ft^3

Therefore, the specific weight of the fluid in the container is 2950 lbf/ft^3, which corresponds to answer choice (a).

Explanation:

A cylindrical bar of metal having a diameter of 20.5 mm and a length of 201 mm is deformed elastically in tension with a force of 46300 N. Given that the elastic modulus and Poisson's ratio of the metal are 60.5 GPa and 0.33, respectively, determine the following: (a) The amount by which this specimen will elongate in the direction of the applied stress. (b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

Answers

Answer:

a) The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

b) The change in diameter of the specimen is  - 0.015 mm

Explanation:

Given the data  in the question;

(a) The amount by which this specimen will elongate in the direction of the applied stress.

First we find the area of the cross section of the specimen

A = \(\frac{\pi }{4}\) d²

our given diameter is 20.5 mm so we substitute

A = \(\frac{\pi }{4}\) ( 20.5 mm )²

A = 330.06 mm²

Next, we find the change in length of the specimen using young's modulus formula

E = σ/∈

E = P/A × L/ΔL

ΔL = PL/AE

P is force ( 46300 N), L is length ( 201 mm ), A is area ( 330.06 mm² ) and E is  elastic modulus (60.5 GPa) = 60.5 × 10⁹ N/m² = 60500 N/mm²

so we substitute

ΔL = (46300 N × 201 mm) / ( 330.06 mm² × 60500 N/mm² )

ΔL =  0.466 mm

Therefore, The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

Using the following relation for Poisson ratio

μ = -  Δd/d / ΔL/L

given that Poisson's ratio of the metal is 0.33

so we substitute

0.33 = -  Δd/20.5 / 0.466/201

0.33 = -  Δd201 / 20.5 × 0.466

0.33 = - Δd201  / 9.143

0.33 × 9.143 =  - Δd201

3.01719 = -Δd201

Δd = 3.01719 / - 201

Δd  = - 0.015 mm

Therefore, The change in diameter of the specimen is  - 0.015 mm

For one-family dwellings, the service disconnecting means must have a rating of at least ___ amperes, 3-wire.

Answers

The rating of the service disconnecting means for a single-family home must be at least 100 amperes, 3-wire.Therefore, 100 amperes is the required minimum rating of service size for a one-family home.

What is the service's required minimum ampere rating?

NEC 230.79 (C) states that the rating of the service disconnecting mechanism for a one-family residence must not be less than 100 amperes, 3-wire.Therefore, 100 amperes is the required minimum rating of service size for a one-family home. In one enclosure, six switches or circuit breakers.Since the 1937 edition of the NEC, the number of switches or sets of circuit breakers that can be utilized as the service disconnecting mechanism to separate a building's premises wiring from the utility provider's conductors can range from one to six. The combined ratings of the circuit breakers, if the disconnecting method consists of more than one switch or circuit breaker, must not be less than the calculated load as established by Art. The 98 amp load for the single-family home will be supplied by a 100 amp electrical service.100 x 83 percent equals 83 amps.The bare minimum service conductor is this one. A revision made to the 2020 NEC mandates that an emergency disconnect be used in accordance with section 230.85.This disconnect is meant to allow emergency personnel to turn off the electricity to the entire house before entering to deal with the situation. Any combination of the following is authorized for the two to six service disconnecting means:separate enclosures, each with a method to disconnect the main service.a main service disconnecting mechanism built inside each panel board enclosure. All primary conductors of transformers that are not grounded must be disconnected using a disconnect.Unless the location of the disconnect is clearly written on the transformer and the disconnect is lockable, as is depicted in the Figure, it must be placed within sight of the transformer.

Consider a simple ideal Rankine cycle and an ideal regenerative Rankine cycle with one open feedwater heater. The two cycles are very much alike, except the feedwater in the regenerative cycle is heated by extracting some steam just before it enters the turbine. Hence, the simple ideal Rankine cycle is more efficient than the ideal regenerative Rankine cycle. How would you compare the efficiencies of of these two cycles?

Answers

Answer:

They both have the same efficiency.

Explanation:

The simple ideal Rankine cycle and an ideal regenerative Rankine cycle with one open feedwater heater would both have the same efficiency because the extraction steam would just create a mini cycle that recirculates. The energy given to the feedwater heater is proportional to the added heat in the boiler to the feedwater in the simple cycle to raise its temperature to the same boiler inlet condition.

Therefore in comparison, the efficiency is the same for both.

Answers

Both Technician A and Technician B are correct regarding the light film of oil observed on the upper area of a shock absorber.

Technician A says that the condition of the light film of oil observed on the upper area of a shock absorber should be considered normal. Technician B says that during cold weather, a rod seal may bleed fluid, causing the oil film. Both of them are correct because a light film of oil on the upper area of a shock absorber may result from any of the following: Heat generated during shock operation and component temperature differences may cause oil to expand and migrate up the piston rod, which may appear as a light film on the upper part of the shock absorber's housing.

During cold weather, a rod seal may bleed fluid, resulting in an oil film on the shock absorber's upper area. During cold weather, fluid seepage past a seal due to lower viscosity is typical. Leakage is occasionally observed when the shock absorber has been in operation for a longer period. A certain amount of leakage past the rod seal and out the weep hole is typical in most high-pressure hydraulic systems. This leakage might be misting or a trickle of fluid.

Answers

The hot iron's initial temperature is 157545°C.

What is iron?

Iron has the atomic number 26 and the chemical symbol Fe. It is a metal from the first transition series and group 8 of the periodic table.

Given mass of the iron mi = 400 kg

Specific heat capacity of iron Ci; = 0.04 Jkg⁻¹k⁻¹

Mass of water Mw = 30 kg

Specific heat capacity of water C w = 4200 Jkg⁻¹ k⁻¹

Temperature of water Tw = 10°c

Mass of Calorimeter Mc = 120 kg

Specific heat capacity of Calorimeter Cc = 0.1 Jkg⁻¹K⁻¹

Final temperature of the mixture of T f = 30°c

Let Ti be the initial temperature of the iron.

We know that, heat lost and heat gained will be equal.

So,

Mc Cc ( T f - 10 ) + Mw C w ( T f - 10 ) + Mi Ci; ( T f - T i ) = 0.

Waste cooking oil is to be stored for processing by pouring it into tank A, which is connected by a manometer to tank B. The manometer is completely filled with water. Measurements indicate that the material of tank B will fail and the tank will burst if the air pressure in tank B exceeds 18 kPa. To what height h can waste oil be poured into tank A? If air is accidentally trapped in the manometer line, what will be the error in the calculation of the height?

Answers

KINDLY NOTE that there is a picture in the question. Check the picture below for the picture.

==================================

Answer:

(1). 1.2 metres.

(2). There is going to be the same pressure.

Explanation:

From the question above we can take hold of the statement Below because it is going to assist or help us in solving this particular Question or problem;

" Measurements indicate that the material of tank B will fail and the tank will burst if the air pressure in tank B exceeds 18 kPa."

=> Also, the density of oil = 930

That is if Pressure, P in B > 18kpa there will surely be a burst.

The height, h the can waste oil be poured into tank A is;

The maximum pressure  = height × acceleration due to gravity × density) + ( acceleration due to gravity × density × height, j).

18 × 10^3 = (height, h ×  10 × 930) + 10 × (2 - 1.25) × 1000.

When we make height, h the Subject of the formula then;

Approximately, Height, h = 1.2 metres.

(2). If air is accidentally trapped in the manometer line, what will be the error in the calculation of the height we will have the same pressure.
