A water piping system is 3000 ft of NPS 20-inch pipe that has three gate valves, one globe valve, one lift check valves, three 90o elbows, and two standard tees through the flow. Calculate the total pipe length that will include all the straight pipe and valves and fittings. Calculate the pressure drop due to friction if the average flow rate is assumed to be 6.7 ft3/s. Take the value of the Darcy friction factor from Problem (1).

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

Analyze the factors that influence the choice between the following pairs of processes to make the products indicated: i) sand casting versus die casting of an electric-motor housing ii) thread rolling versus machining of a bolt for high-strength application. (co3/c5)
