Chapter 13, Problem 13.64PP
A pump draws propane at 
F (sg
from a tank whose level is 
in above the pump inlet. The energy losses in the suction line total 
ft and the atmospheric pressure is 
psia. Determine the required pressure above the propane in the tank to ensure that the NPSH available is at least 
ft.

A "spa tub" is to be designed to replace bath tubs in reno-
vations. There are to be 6 outlet nozzles, each with a di-
ameter of 12 mm, and each should have an outlet velocity
of 12 m/s. What is the required flow rate from the single
pump that supplies all of these nozzles? If there is one
suction line leading to the pump, what is the minimum
diameter to limit the velocity at the inlet of the pump to
2.5 m/s?
