Q3. A pump draws water through a 20-cm suction pipe and discharges it through a 10- cm pipe in which the velocity is 3 m/s (Fig. 3). The 10-cm pipe discharges horizontally into air at point C. To what height h above the water surface at A can the water be raised if 35 kW is delivered to the pump? Assume the head loss in the pipe between A and C is egual to 2Y?/2g.

An ideal water jet with volume flow rate of 0.05 m^ 3 / s strikes a flat plate placed normal to its path and exerts a force 1000 N Considering the density of water as 1000 kg / (m ^ 3) , find the diameter (in mm) of the water jet.
A large lawn sprinkler with two identical arms is used to generate electric power by attaching a generator to its rotating head. Water enters the sprinkler from the base along the axis of rotation at a rate of 5 gal/s and leaves the nozzles in the tangential direction. The sprinkler rotates at a rate of 180 rpm in a horizontal plane. The diameter of each jet is 0.5 in, and the normal distance between the axis of rotation and the center of each nozzle is 2 ft. Determine the maximum possible electrical power produced.

Suppose that there is a 4-cm water jet with a velocity of 15 m/s which hits a vertical plate with a mass on 800 kg. This plate is mounted on a track which is nearly frictionless and starts out not moving. when the jet strikes the plate, water leaves by splashing out in the plane of the plate. what is the acceleration of the plate when the jet first hits it? What is the velocity of the plate after 60 seconds? Assume that the momentum correction factor s 1.04.
The open stream of water seen in the following picture emerges from a nozzle into the atmosphere at sea level, where it then collides with a stagnation tube. If we exclude losses and assume that the pressure at the centerline of section 1 is 110 kPa, we can estimate that the (a) the mass flow measured in kilograms per second (kg/s), and (b) the height, measured in meters, of the fluid in the stagnation tube.
Water is flowing from a garden hose . A child places his thumb to cover most of the hose outlet, causing a thin jet of high-speed water to emerge. The pressure in the hose just upstream of his thumb is 400 kPa. If the hose is held upward, what is the maximum height that the jet could achieveve?
Water flows upward in a vertical 300-mm pipe at the rate of 0.222 m /s. At point A in the pipe, the pressure is 210 kPa. At B, 4.57 m above A, the diameter is 600 mm, and the lost head A to B equals 1.83 m. Determine the pressure at B.
