Water at 20°C is pumped at a constant rate of 9 m3/h from a large reservoir resting on the floor to the open top of an experimental absorption tower. The point of discharge is 5 m above the floor, and friction losses in the 50-mm pipe from the reservoir to the tower amount to 2.5 J/kg. At what height in the reservoir must the water level be kept if the pump can deliver only 0.1 kW?Determine the average velocity of the water at the starting point (on the surface of the reservoir)
Water enters a centrifugal pump axially at atmospheric pressure at a rate of 0.09 m3/s and at a velocity of 5 m/s, and leaves in the normal direction along the pump casing, as shown in Determine the force acting on the shaft (which is also the force acting on the bearing of the shaft) in the axial direction.
The pipe elbow below discharges water at rate of SN/100 (m3/s) into the atmosphere at section 2. The total volume of the passage between sections 1 and 2 is equal to 0.2 m3 and the total mass of the elbow material between sections 1 and 2 is equal to 10 x SN (kg). Neglect any friction losses.
Calculate the horizontal and vertical forces acting on the elbow. Also, calculate the resultant force and angle of force on the elbow.

- A 25 hp suction pump operating at 70.00% efficiency draws water from a suction line whose diameter is 184 mm and discharges into the air through a line whose diameter is 134 mm. The velocity in the 134 mm line is 1.9 m/s. If the pressure at point A in the suction pipe is -28 kPa (negative sign indicates the pressure is below the atmosphere), where A is 1.8 m below B on the 134 mm line, determine the maximum elevation above B to which water can be raised assuming a head loss of 2.4 m due to friction. Show step by step explanation.arrow_forwardWater accelerated by a nozzle to 33 m/s strikes the vertical back surface of a cart moving horizontally at a constant velocity of 9 m/s in the flow direction. The mass flow rate of water through the stationary nozzle is 30 kg/s. After the strike, the water stream splatters off in all directions in the plane of the back surface. Determine the force that needs to be applied by the brakes of the cart to prevent it from accelerating. If this force were used to generate power instead of wasting it on the brakes, determine the maximum amount of power that could ideally be generated.arrow_forwardA 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.arrow_forward

The water velocity at the hose outlet is 10 m/s relative to the skater. If she is initially standing still, determine (a) the velocity of the skater and the distance she travels in 5 s and (b) how long it will take to move 5 m and the velocity at that moment.arrow_forwardA 2-in water jet with a velocity of 130 fps strikes a single vane moving in the same direction of the jet at a velocity of 50 fps.
