Consider the compression step of an ordinary vapor compression cycle using ammonia as the working fluid. The inlet to the compressor is saturated vapor at 10 C and approximately 6.25 bar, the outlet is superheated vapor at 10 bar. Approximate the non-ideal PVT-behavior of ammonia in this region by the van der Waal’s EOS. Using the data Tc = 132.4 C, Pc=112.8 bar, and Cv=36.1 kJ/kmol-K (and no other data). Required:
Derive a set of equations that can be solved simultaneously for the temperature of the outlet stream, assuming the compressor is reversible.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

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.
