A pump delivers 500 GPM water with a suction line 6 in. diameter. The reservoir is pressurized with to 17 psia. The required
NPSH_R


is 15 ft. Due to the use of a filter and several bends on the suction line, the total loss coefficient adds up to K = 35. a) Find the maximum distance between pump centerline and water surface in the tank. Water is at 80 F for which,
ρ
= 62.5 lbm/ft3 and
µ
= 2.1 lbm/ft·h. b) Find the
NPSH_A

if the pump is located 5 ft below the source reservoir water level.
