The pressure drop in a pipe is function of the density and viscosity of the fluid being transported, the average velocity of the flow, and the length, the diameter, and the roughness of the pipe. Using the Buckingham Pi Theorem determine the non–dimensional parameters representing this problem. Choose the density, average velocity and diameter of the pipe as repeating variables.

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
