Water ( \rho = 62.4 lbm/ft3, \mu = 0.88x10-3 lbm/ft-s) flows from a large pressurized tank to a higher tank open to the atmosphere. the elevation difference between surface levels is 3 ft. the tanks are connected by 20 ft of 3½" sch 40 pvc pipe, a sudden contraction, a total of 40 ft of 2" sch 120 pvc pipe, a half open gate valve, and then two standard radius elbows (r = 9"). find the pressure, p1, that generates a volumetric flow rate of 8.5 cfm between the tanks. (4.58 psig)

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

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information
