A jet of water with velocity 35 m/s strikes a series of radial curved vane mounted on a wheel which is rotating at 200 rpm. The jet makes an angle 30° with the tangent to the wheel at inlet, and leaves the wheel with a velocity 5 m/s at angle of 140° to the tangent to the wheel at the outlet. The outer and inner radii of the wheel are 70 cm and 35 cm, respectively. A. Determine the Inlet Vane Angle, in degrees.
The impeller of a centrifugal blower has a radius of 15 cm and a blade width of 6.1 cm at the inlet, and a radius of 30 cm and a blade width of 3.4 cm at the outlet. The blower delivers atmospheric air at 20°C and 95 kPa. Disre- garding any losses and assuming the tangential components of air velocity at the inlet and the outlet to be equal to the impeller velocity at respective locations, determine the volu- metric flow rate of air when the rotational speed of the shaft is 800 rpm and the power consumption of the blower is 120 W. Also determine the normal components of velocity at the inlet and outlet of the impeller.
A 5-cm-diameter horizontal jet of water, with velocity 30 m/s, strikes the tip of a horizontal cone, which deflects the water by 60° from its original direction. How much force is required to hold the cone against the water stream?
Air flows steadily at low speed through a horizontal nozzle (by definition a device for accelerating a flow), discharging to atmosphere. The area at the nozzle inlet is 0.1m². At the nozzle exit, the area is 0.02m². Determine the gage pressure required at the nozzle inlet to produce an outlet speed of 50 m/s.
A fluid moves in a steady flow manner between two sections in a flow line. At the entrance section A1 = 1m², V1= 0.5 m/s, P1= 4kgm/m³. At the exit section: A2 = 0.2m², V2= 0.20m³/kgm. Calculate the mass flow rate in kg/s and the speed at section 2 in m/s.

A cylindrical pipe with a cross-sectional radius r = 1.40[cm] is plunged into a l = 2.30[m] tall open water drum that is initially completely filled with water (pwater = 1000 [kg/m3]). The pipe goes h1 = 0.35 [m] above the drum before dropping down h2 = 3.50 [m] below the base of the drum as shown. The cross-sectional radius of the top side of the pipe is R = 2.20 [cm].A. How fast is the water going out of this pipe?B. What's the liquid's pressure at the top of the pipe? Assume that the system is exposed to 1.00 [atm] of air pressure.C. What's the maximum height the pipe can go above the drum before the water stops flowing out of the pipe? For liquid flow to be continuous, the liquid’s pressure must not fall before its vapor pressure. Assume that vapor pressure, in this case, is 2.30 [kPa].
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.
