Oxygen enters an insulated 12.2-cm-diameter pipe with a velocity of 72 m/s. at the pipe entrance, the oxygen is at 240 kpa and 20°c; and, at the exit, it is at 200 kpa and 18°c. calculate the rate at which entropy is generated in the pipe. kw/k

Fluids at rest possess no flow energy. 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
