An air-conditioning system is designed to have a ductwith a rectangular cross section 1 ft by 2 ft, as shown. Duringconstruction, a truck driver backed into the duct and made it atrapezoidal section, as shown. The contractor, behind schedule,installed it anyway. For the same pressure drop along the pipe,what will be the ratio of the velocity in the trapezoidal duct tothat in the rectangular duct? Assume the Darcy-Weisbach resistance coefficient is the same for both ducts.
The value of (NPSH) for a pump is given by the manufacturer as 10 ft. Water is being pumped from a reservoir at min atmospheric pressure at a rate of 30 ft /s to a tank at atmospheric pressure. The water level in the reservoir is 5 ft below the pump. If the total head loss in the suction pipe is 5 ft, is the pump safe from cavitation effects? If a 2-in schedule 40 pipe of 150 m length was used downstream of the pump, what is the power delivered to the fluid? You may assume that the friction factor in the pipe is equal to 0.004.

The velocity of flow through the impeller is constant and equal to 3m/s. The vanes are set back at an anhgle of 30°at the outlet. If the outer diameter of the impeller is 600mm and width at outlet is 50mm, determine: a- Vane angle at inlet. b- Work done per second by impeller. c- Manometric efficiency.
2. Water from a reservoir is pump over a hill through a pipe 900mm in diameter and a pressure of one kg/cm² is maintained at the pipe discharge where the pipe is 85m from the pump centerline. The pumps have a positive suction head of 5m. Pumping rate or the pump at 1000 rpm is 1.5m³/sec. Friction losses is equivalent to 3m of head loss. What is the head that should the pump cover for the system?
