23. The nozzle which furnished the water to a certain hydraulic turbine 280 mm in diameter and has a coefficient of velocity and discharge of 0.98 and 0.95 respectively. The nozzle supplied from 60 cm in diameter pipe in which water approached the nozzle with a total head of 335 m. Compute for the power in kN/s delivered by the jet to the turbine
. It has been assumed that the velocity of the jet is uniform over its cross-section. plow is the momentum of the jet affected if this is not the case? Consider a jet with a cross-sectional area (4) in which the velocity is 0.5vo over half of the area and 1.5vo over the other half. The discharge is the same as if the velocity were vo over the whole, namely: W = voA. Show that the delivery rate of momentum in the jet is 1.25Wvo, i.e., 25% greater than the uniform velocity over the cross-section.
A jet of water having a velocity of 30 m/s strikes a series of radial curved vanes mounted on a wheel which is rotating at 300 rpm. The jet makes an angle of 30 ∘ with the tangent to the wheel at inlet and leaves the wheel with a velocity of 4 m/s at an angle of 120 ∘ to the tangent to the wheel at outlet. Water is flowing from outward in a radial direction. The outer and inner radii of the wheel are 0.6 m and 0.3 m respectively. Determine: (a) Vane angles at inlet and outlet , (b) Work done per second per kg of water, and (c) Efficiency of the wheel.

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.

A jet of water is coming out from an inverted conical tank, which is full of water, through an orifice located in the side at 3 m from the top along the side of the tank. The tank is 4√5 m high and has a diameter at the top of 2 m. The vertex of the tank is 2 m above the ground level. If the coefficient of discharge is 0.62 and coefficient of velocity is 0.98, find the horizontal distance measured from the center of the conical tank to the point on the ground where the jet landed.
Water (@75C) flows horizontally in a pipe at a rate of 1.6 m3 / min . The dia of the outlet is 2 inches. It enters a 3 inches 45 deg. elbow and is diverted upwards into a connecting pipe.

A horizontal water jet with a flow rate of V. and crosssectional area of A drives a covered cart of mass mc along a level and nearly frictionless path. The jet enters a hole at the rear of the cart and all water that enters the cart is retained, increasing the system mass. The relative velocity between the jet of constant velocity VJ and the cart of variable velocity V is VJ − V. If the cart is initially empty and stationary when the jet action is initiated, develop a relation (integral form is acceptable) for cart velocity versus time.
