pump selection can be bas<strong>ed</strong> on thermodynamic tables. For a constant<br />

throughput in units of st<strong>and</strong>ard cubic feet per day (SCFD), the inlet <strong>and</strong><br />

outlet pump capacity in GPM will change with change in specific volume<br />

(Figure 10-36).<br />

Calculation Proc<strong>ed</strong>ure<br />

The following example assumes the use of appropriate Thermodynamie<br />

Tables.<br />

Given<br />

Step L Find Inlet Conditions<br />

A. From P t , <strong>and</strong> Tj, find HI, V } , <strong>and</strong> Si from tables<br />

B. Calculate 7,, SG b Q,, <strong>and</strong> H<br />

C. Select Pump<br />

Select pump for 5220 GPM <strong>and</strong> total pump head of 693 ft<br />

Note, pump efficiency in this example is 85%.<br />

D. Calculate BHP
