Example 3-5 NPSH Available in Open Vessel Not at Sea Level

Conditions vessel is at altitude 1500 ft, where atmospheric pressure is 13.92 psia = pa, 

Liquid water at 150°F, vapor pressure Pvp = 3.718 psia SpGr = 0.982 

Assume vessel liquid level is 12 ft below centerline of pump, SL = —12. 

The worst condition case should be calculated using
