For the system shown in Fig. 8.17, compute the power delivered by the pump to the water to pump 50 gal/min of water at 60 ° F to the tank. The air in the tank is at 40 psig. Consider the friction loss in the 225 -ft-long discharge pipe, but neglect other losses. Then, redesign the system by using a larger pipe size to reduce the energy loss and reduce the power required to no more than 5.0 hp.

The net force exerted on the piston by the exploding fuel-air mixture
and friction is 5 kN to the left. A clockwise couple M = 200 N-m acts on the crank AB.
The moment of inertia of the crank about A is 0.0003 kg-m2
. The mass of the
connecting rod BC is 0.36 kg, and its center of mass is 40 mm from B on the line from B
to C. The connecting rod’s moment of inertia about its center of mass is 0.0004 kg-m2
.
The mass of the piston is 4.6 kg. The crank AB has a counterclockwise angular velocity
of 2000 rpm at the instant shown. Neglect the gravitational forces on the crank,
connecting rod, and piston – they still have mass, just don’t include weight on the FBDs.
What is the piston’s acceleration?
