The chilled water system for a 25-story building has a pump located at ground level. The lost head in a vertical riser from the pump to an equipment room on the twenty-fifth floor is 30 ft (9 m) of water, and the pump produces 250 ft (76 m) of head. What is the pressure on the suc- tion side of the pump for a pressure of 8 psig (55 kPa gage) to exist in the riser on the twenty- Gith floor? Assume 12 ft (3.7 m) of elevation per floor.
