Answer:
Option B is correct
Explanation:
Let
Higher temperature = 
Lower temperature = 
We know that COP is given by
We see that COP is depends only on the temperature difference & Temperature difference is maximum for the Carnot cycle.
Therefore the COP of reversible refrigeration cycle is always less then the COP of an irreversible refrigeration cycle when each operates between the same two thermal reservoirs.
Therefore option B is correct
This is about method of taking inside measurement with a tape.
<u><em>Option A is the correct answer.</em></u>
- Inside measurement is usually taken with the aid of an inside micrometer. This will give us an exact measurement. This is because when making use of an inside micrometer for inside measurement, the total length of the inside micrometer is equal to the overall length of whatever is being measured.
- We have seen how the inside micrometer is used whereby the entire body is also included in whatever is being measured. Applying this same concept to using a tape, we can simply say that we will add the tape length to the measuring case to get the inside measurement.
- From the definitions and comparisons above, we can see that we will have to add the length of the tape measure case when taking inside measurements and other options aside Option A are not correct.

Answer:
Check the 2nd, 3rd and 4th statements.
Explanation:
Answer:
Pre-Flush:
It is also known as In-line Equalization. In this stage of flow equalization, all the flow passes through the equalization basin. It helps in reduction of fluctuation in pollutants concentration and flow rate and helps to control short term surges with the use of basin.
Post-Flush:
Another name for this stage is Off-line Equalization. In this stage, only overflow above a predetermined standard is diverted into the basin. It helps in reducing the fluctuations in loading by a considerable amount and helps to reduce the pumping requirement. It is basically used to capture "first flush" from combined collection systems.
