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, \(800 \mathrm{lb}\) of water is collected in the catch tank in \(15 \mathrm{~s}\). The pump power input to the fluid during this period is \(700 \mathrm{ft} \cdot \mathrm{lb} / \mathrm{s}\). Calculate the water velocity in the pipe and the mechanical energy loss \(\left(\mathrm{ft} \cdot \mathrm{lb} / \mathrm{lb}_{\mathrm{m}}\right)\) in the pipe and valve.
