At 1.2mpa pressure and 50c

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53

The answer of the given question based on the Preparing a set of level notes for the data listed are given below,

Misclosure is the difference between the sum of the foresight (FS) readings and the sum of the backsight (BS) readings in a leveling circuit. Ideally, the sum of the FS readings should be equal to the sum of the BS readings, but due to errors in measurement or instrument, this may not be the case

Level notes:

To check the misclosure, we need to add up the backsight (BS) and foresight (FS) readings separately and compare them.

Sum of BS = 4.368 m + 3.730 m + 3.598 m = 11.696 m

Sum of FS = 6.907 m + 4.680 m + 8.464 m = 20.051 m

In this case, the misclosure is:

Misclosure = Sum of FS - Sum of BS = 20.051 m - 11.696 m = 8.355 m

The average of the FS readings is 6.6837 m, so we need to subtract 8.355 m / 3 = 2.785 m from each of the FS readings. The adjusted FS readings are:

FS1 = 6.907 m - 2.785 m = 4.122 m

FS2 = 4.680 m - 2.785 m = 1.895 m

FS3 = 8.464 m - 2.785 m = 5.679 m

The adjusted level notes are:

The adjusted FS readings now add up to the adjusted sum of BS readings, which is 11.696 m. This means that the misclosure has been corrected and the level notes are now balanced.

Answer:

If the vehicle is accelerating from 20 mph using 100 kW of power, then:

- The motor is providing 60 kW of power to the vehicle.

- The generator is providing 30 kW of power to the vehicle.

- The engine is providing 10 kW of power to the generator, so the total power output of the engine is 70 kW, but only 30 kW of that is going directly to the vehicle.

During acceleration from 20 mph using 100 kW of power, the power output of the motor is 60 kW, the power output of the generator is 30 kW, and the power output of the engine is 70 kW.

The total power output during acceleration is given as 100 kW.

The power output of the motor is 60 kW, which means that the motor is providing 60% of the total power.

The power output of the generator is 30 kW, which means that the generator is providing 30% of the total power.

The power output of the engine is 70 kW, which means that the engine is providing 70% of the total power.

Therefore, the sum of the power outputs of the motor, generator, and engine is 60 kW + 30 kW + 70 kW = 160 kW, which is 60 kW more than the total power input of 100 kW.

This extra power output is due to the energy stored in the vehicle's kinetic energy during acceleration.

(b) Moving the test setup to a room with proper temperature control and providing training to staff are proper corrective actions.

The most appropriate clause in ISO/IEC 17025:2017 to raise this nonconformity would be Clause 7.6.1 - Control of Monitoring and Measuring Equipment. This clause requires laboratories to have processes in place to ensure that monitoring and measuring equipment used for testing and calibration are controlled and calibrated to provide valid results.

In this case, the temperature inside the room during the test demonstration did not meet the specified requirement of 22±1°C, indicating a nonconformity in the control of the monitoring and measuring equipment (temperature control system).

Moving the setup of the test to another room with a temperature control range of 22±1°C and providing training to all laboratory staff can be considered as proper corrective actions. By moving to a room with better temperature control, the laboratory ensures that future tests are conducted within the specified temperature range. This helps in meeting the test standard requirements and improves the accuracy and reliability of the test results.

Providing training to all laboratory staff is also important as it ensures that everyone is aware of the temperature requirements and understands the importance of maintaining and monitoring the temperature during tests. This helps in preventing similar nonconformities in the future and promotes a culture of adherence to standards and procedures.

Overall, these corrective actions address the identified nonconformity by implementing measures to rectify the temperature control issue and enhance the laboratory's ability to consistently provide accurate and reliable test results.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The phase angle is 180°.

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

To calculate the required processing and assembly operations, workers, and total floor space for the new factory, we can break down the problem into smaller parts and analyze each element.

(a) Processing and assembly operations:

Number of components made in the factory: 250 components * 35% = 87.5 (round up to 88 components)

Processing operations for components: 88 components * 8 processing operations = 704 processing operations

Assembly operations for final product: 1 assembly operation (as each product is assembled in one workstation)

Total operations = 704 processing operations + 1 assembly operation = 705 operations

(b) Number of workers (direct labor only):

Processing workers: 704 processing operations / 1 (one worker per work cell) = 704 workers

Assembly workers: 13 models * 1000 units/model = 13,000 units/year

Assembly time per unit: 48 min/unit = 0.8 hr/unit

Assembly time for all products: 13,000 units * 0.8 hr/unit = 10,400 hr

Assembly workers required: 10,400 hr / 2,000 hr/shift = 5.2 (round up to 6 workers)

Total workers = 704 processing workers + 6 assembly workers = 710 workers

(c) Total floor space required:

Processing floor space: 704 work cells * 25 m2/cell = 17,600 m2

Assembly floor space: 6 workstations * 25 m2/station = 150 m2

Total production area: 17,600 m2 + 150 m2 = 17,750 m2

Additional allowance (45%): 17,750 m2 * 45% = 7,987.5 m2

Total floor space = 17,750 m2 + 7,987.5 m2 = 25,737.5 m2 (round to 25,738 m2)

In summary, the XYZ Company will require:
