A 2-in. diameter orifice plate is inserted in a 3-in. diameter pipe. If the water flow rate through the pipe is 0.90 cfs. (take your density equal to 1.94 slugs/ft3, and absolute viscosity equal to 2.34 x 10-5 lb. s/ft2). What is the velocity of the air (in ft/s) passing through the device before the orifice plate? (Give your answer in two decimals, do not enter any units)

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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
