Apump steadily delivers water through a hose terminated by a nozzle. the exit of the nozzle has a diameter of 2.5 cm and is located 4 m above the pump inlet pipe, which ahs a diameter of 5.0 cm. the pressure is equal to 1 bar at both the inlet and the exit, and the temperature is constant at 20 degrees c. the magnitude of the power input required by the pump is 8.6 kw, and the acceleration of gravity is g= 9.81m/s2. determine the mass flow rate delievered by the pump in kg/s.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

The temperature of air decreases as it is compressed by an adiabatic compressor. 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
