A pump steadily draws water from a pond at 20 lb/s. Pressure at the inlet is 14.7 psi ,the temperature is 68 degrees F and the velocity is 10 ft/s. At the exit the pressure is 20 psi, temperature is the same at 68 degrees, and the velocity is 40 ft/s. The outlet is 50 ft above the inlet. Determine the power required by the pump in both Btu/s and hp. Local gravity is 32.0 ft/s^2.
The system is at rest in the position shown, with the 12-lb collar A resting on the spring (k = 20 lb/ft), when a constant 30-lb force is applied to the cable. What is the velocity of the collar when it has risen 1 ft? The collar is attached to th..
