Air at 1 bar and 158C enters the compressor of an ideal cold air-standard regenerative Brayton cycle. The pressure at the compressor exit is 10 bar and the maximum cycle temperature is 11008C. For k 5 1.4, determine (a) the net work developed, in kJ per kg of air flowing. (b) the energy added by heat transfer, in kJ per kg of air flowing. (c) the thermal efficiency. (d) Using Eq. (b) of Problem 9.65, check the value obtained in (c) for thermal efficiency.

Explanation:

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
