Apump is used to transfer h2o from the surface of a lake into a tank where pressure is maintained at 350 kpa. the pump operates in steady flow with an efficiency of 0.6 and has an iniet volume flow rate of 0.5m^3/s. making good engineering assumptions, do the following: a) calculate the actual power required to drive the pump. b) determine the volume flow rate at the discharge of the pump. c) show this process on a t-s diagram including the saturation curve.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
