Figure shown below shows a water system such as might be found in a central equipment room, the units a. b. and c are heat exchanger units. Size the piping and specify the pumping requirements. (V_max

Solution

As asked,we need to state the basic requirements for pipe sizing and pump designing.

Most of all,the most important factor we need is the Flowrate.

We need to know the Maximum Flowrate which can be found out by summing up all the GPM of operating devices.

Adding Chiller+A+B+C Flowrates = 340GPM.

Unit A pipe size will be 3 inches because it\'s flow rate is 80Gpm in accordance with the table.

Unit B and Unit C will have 2 1/2 inch pipe because it\'s Flowrates is 60Gpm.
