Step 2. Find Outlet Conditions<br />

A, Assume constant entropy Si = S 2<br />

B. From P 2 = 1650 psia <strong>and</strong> S 2 = 0,7877 Btu/lb °R interpolate<br />

tables to find H 2 , V 2 <strong>and</strong> T 2<br />

C. Calculate AH, <strong>and</strong> AH !<br />

Step 3, Correct Outlet Conditions For Pump<br />

Efficiency<br />

A. With P 2 remaining same calculate H c<br />

B. From HC <strong>and</strong> P 2 interpolate tables to find V c , S c , <strong>and</strong> T c<br />

C. Calculate y c <strong>and</strong> Q 2
