Water is pumped steadily through the apparatus shown in Fig. P5.111. The pipe area and gage pressure are shown for both outlet sections 1 and 2. Assume that the \(40^{\circ} \mathrm{F}\) water is frictionless and incompressible. Compute the horsepower input to the pump. The total volume flow rate \(Q_{T}=1.0 \mathrm{ft}^{3} / \mathrm{s} . D_{a}=4.0 \mathrm{in}\).
