A closed system consisting of 4 lb of a gas undergoes a process during which the relation between pressure and volume is pV^n = constant. The process begins with p1=15lbf/in.2, v1=1.25ft3/lband ends with p2=53lbf/in.2, v2=0.5 ft3/lb. Determine
(a) the volume, in ft^3, occupied by the gas at states 1 and 2 and
(b) the value of n.
(c) Sketch Process 1-2 on pressure-volume coordinates. Is this an expansion or compression process? Explain?

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.
