Consider the power system as designed below. The duty fluid is water, and has a mass flow 0.75 kg/ s and all piping through which the liquid flows has diameter 1'', while the steam pipes have diameter 3''. Between the pump and the spot 4, there are 20m of carbon steel pipe. Six 90° curves, two globe valves and a filter with a load loss equivalent to 3 times the load loss on a gate valve. Find the minimum power of the pump.
A 0.453-Kg mass attached to a light spring elongates it by 7.87mm. Determine the natural frequency of the system.
A short 60-mm-diameter circular bar is made of a material for which the maximum safe compressive stress is 80 MPa and the maximum safe shearing stress is 30 MPa. Determine the maximum axial compressive force that can be safely applied.
