The open-ended polyvinyl chloride pipe has an inner diameter of 4 in. and thickness of 0.2 in. It carries flowing water at 57psi pressure. If the flow of water within the pipe is stopped due to the closing of a valve, determine the state of stress in the walls of the pipe. Neglect the weight of the water. Assume the supports only exert vertical forces on the pipe. (Picture is a horizontal pipe on 6 supports)
a heat pump operates on the ideal vapor compression refrigeration cycle with r-134a as the working fluid between the
5 kg of steam contained within a piston-cylinder assembly undergoes an expansion from state 1 where the specific
Determine the force in member BC. After the truss is sectioned use a single equation of equilibrium for the calculation of each force. State if these member is in tension or compression. Take F1 = 2 kN , F2 = F3 = 3.8kN , F4 = 5 kN, F5 = 3 kN.

an industrial water shutoff valve is designed to operate with 30 lb of effort force. The valve will encounter 200 lb of resistance force applied to a 1.5 in. diameter axle. what is the required wheel diameter to overcome the resistance force?
Refrigerant 134a at a flow rate of 0.5 lb/s enters a heat exchanger operating at steady state as a saturated liquid at 0 0F and exits at 20 0F. A separate air stream enters at 120 0F and exits at 77 0F. The heat exchanger is insulated such that there..
