A 95-ft3/s water jet is moving in the positive x-direction at 17 ft/s. The stream hits a stationary splitter, such that half of the flow is diverted upward at 45° and the other half is directed downward, and both streams have a final average speed of 17 ft/s. Disregarding gravitational effects, determine the x- and z- components of the force required to hold the splitter in place against the water force.
A 100-ft3/s water jet is moving in the positive x-direction at 18 ft/s. The stream hits a stationary splitter, such that half of the flow is diverted upward at 45° and the other half is directed downward, and both streams have a final average speed of 18 ft/s. Disregarding gravitational effects, determine the x- and z-components of the force required to hold the splitter in place against the water force.

Two geometrically similar pumps are running at the speed of 1500rpm and 3000rpm. One pump has an impeller diameter of 0.40 m and lifts water at the rate of 0.03 liters/sec against a head of 20 meters. Determine the head, discharge and ratio of powers of said pump of diameter 0.25m.
1. A diverging pipe has diameter of 20cm and 30cm respectively at section 1 and section 2. If the velocity of water at section-1 is 5 m/s, determine the discharge through this pipe. Determine the velocity at section-2. 2. A 50cm diameter pipe, conveying water, branches into two pipes of diameter 30cm and 20 cm respectively. If the average velocity in the 50 cm diameter pipe is 2.5 m/s, find the discharge in this pipe. Also determine the velocity in 20 cm pipe if the average velocity in 30 cm diameter pipe is 1.5 m/s.
A 100-ft3 /s wáter jet hits a horizontally lying stationary splitter, such that half of the mass flow is diverted one way and the other half is diverted the other way, and both streams have a uniform velocity of 18 ft/s.

A 60-kg ice skater is standing on ice with ice skates (negligible friction). She is holding a flexible hose (essentially weightless) that directs a 2-cm-diameter stream of water horizontally parallel to her skates. 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.
Water enters a mixed flow pump axially at a rate of 0.25 m3/s and at a velocity of 5 m/s, and is discharged to the atmosphere at an angle of 75° from the horizontal, as shown . If the discharge flow area is half the inlet area, determine the force acting on the shaft in the axial direction
A lawn sprinkler with three identical arms is used to water a garden by rotating in a horizontal plane by the impulse caused by water flow. Water enters the sprinkler along the axis of rotation at a rate of 45 L/s and leaves the 1.5-cm-diameter nozzles in the tangential direction. The bearing applies a retarding torque of T0 = 40 N·m due to friction at the anticipated operating speeds. For a normal distance of 40 cm between the axis of rotation and the center of the nozzles, determine the angular velocity of the sprinkler shaft.
