Figure P5.115 shows a pump testing setup. Water is drawn

from a sump and pumped through a pipe containing a valve. The

water is discharged into a catch tank sitting on a scale. During a

test run, 800 lb of water is collected in the catch tank in 15 s. The

pump power input to the fluid during this period is 700 ft ∙ lb/s.

Calculate the water velocity in the pipe and the mechanical energy

loss (ft ∙ lb/lbm) in the pipe and valve.
