Anozzle in a horizontal orientation is designed to have steady flowing steam exit it with a velocity of 250 m/s. if the outlet specific enthalpy of the steam is 1,986 kj/kg, what is the required inlet specific enthalpy? assume that heat transfer to the surroundings and the inlet steam velocity are negligible.

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
