The hydraulic cylinder operates the toggle which closes the vertical gate against the pressure of fresh water on the opposite side. the gate is rectangular with a horizontal width of 3.5 m perpendicular to the paper. for a depth h = 3.7 m of water, calculate the required oil pressure p which acts on the 120-mm-diameter piston of the hydraulic cylinder.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

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

Have a greater impact on maintenance productivity than any other support group. (clo5) a)-the top management b)-inventory and purchasing c)-sub-contracting d)-cmms
