Air enters a fan through a duct velocity of 6.3 m/s and an inlet static pressure of 2.5cm of water less than the atmospheric pressure. The air leaves the fan through the duct at a velocity of 11.25 m/s and a discharge pressure of 7.62cm of water above the atmospheric pressure. If, the density of the air is 1.2kg/m3and the fan delivers 9.45m3/s, what is the fan efficiency when the power input to the fan is 13.75 kW at the coupling. Show schematic diagram and provide solutions.
A pump is 2.2 m above the water level in the sump and has a pressure of –20 cm of mercury at the suction side.

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. Determine the work done per unit weight of water, in Newton-Meter per Newton.
At the bottom of a pressurized water tank is a mouth with a diameter of 5 cm, where water is discharged into the atmosphere. The water level is 2 m above the outlet.

The impeller of a centrifugal blower has a radius of 18 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. Disregarding 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 volumetric flow rate of air when the rotational speed of the shaft is 900 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 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].
