Water enters a 13-cm-diameter pipe steadily with a uniform velocity of 2 m/s and exits with the turbulent flow velocity distribution given by u = umax(1 − rr)1/7 . if the pressure drop along the pipe is 10 kpa, determine the viscous force exerted in the pipe by the water flow. take the density of water to be 1000 kg/m3. the average velocity is equal to 0.816 times the max velocity. the viscous force exerted in the pipe by the water flow is 50

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
