Chapter 7, Problem 7.22PP

Figure 7.26 shows the arrangement of a circuit for a hydraulic system. The pump draws oil with a specific gravity of $0.90$ from a reservoir and delivers it to the hydraulic cylinder. The cylinder has an inside diameter of $5.0$ in, and in s the piston must travel

$20$ in while exerting a force of $11000$ lb. It is estimated that there are energy losses of $11.5$ lb-ft/lb in the suction pipe and $35.0$ Ib-ft/lb in the discharge pipe. Both pipes are $\raisebox{1ex}{$$}\!\left/ \!\raisebox{-1ex}{$$}\right.$ -in Schedule $80$ steel pipes. Calculate:

1. The volume flow rate through the pump.

The pressure at the cylinder.

The pressure at the outlet of the pump.

The pressure at the inlet to the pump.

The power delivered to the oil by the pump.
