Refrigerant-134a is compressed from 2 bar, saturated vapor, to 10 bar, 90o C in a compressor operating at steady state. The mass flow rate of refrigerant entering the compressor is 7 kg/min, and the power input is 10.85 kW. Kinetic and potential energy effects can be neglected. a) Determine the rate of heat transfer (kW). b) If the heat transfer occurs at an average compressor surface temperature of 50o C, determine the rate of entropy production (kW/K). c) Determine the rate of entropy production (kW/K), for an enlarged

Find attach the solution

Explanation:

Entropy production is almost the same in (b) and (c) as ~

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.
