In large buildings, hot water in a water tank is circulated through a loop so that the user doesn’t have to wait for all the water in long piping to drain before hot water starts coming out. a certain recirculating loop involves 40-m-long, 1.2-cm-diameter plastic (smooth) pipes with six 90° threaded smooth bends and two fully open gate valves. if the average flow velocity through the loop is 2.5 m/s, determine the required power input for the recirculating pump. take the average water temperature to be 60°c and the efficiency of the pump to be 50 percent.

answer: hi

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.
