Toluene at 35 degrees Celsius is pumped from an open reservoir to a tank kept at a gauge pressure of 150 kPa. The pump itself is 3m below the reservoir, while the discharge tank is 10m above the reservoir. Assuming friction in the suction line is negligible, while in the discharge line the friction head amounts to 7.5 m, determine the net positive suction head available for the pump. If the pump has an efficiency of 65%, determine the total power input. At the given temperature, the density and vapor pressure of toluene are 862 kg/m3 and 40 mmHg

A pump takes water at 60°F from a large reservoir and delivers it to the bottom of an open elevated tank 25 ft above the reservoir surface through a 3 inch ID pipe. The inlet to the pump is located 10 ft below the water surface, and the water level in the tank is constant at 160 ft above the reservoir surface. The pump delivers 150 gal/min. If the total loss of energy due to friction in the piping system is 35 ft·lbf/lb. The pump and its motor have an overall efficiency of 55 %. i. Determine Delta Z (Z2 - Z1) in ft. ii. What is the actual shaft work needed for this particular mass flow rate in (ft-lbf)/s. iii. What is the mass flow rate of the water in lbm/s?

A pump draws water from a reservoir and conveys it to another reservoir 30 m above. The suction pipe is 100 mm in diameter and 10 m long while the delivery pipe is 100 mm in diamter and 150 m long. if the the velocity in the pipe is 3 m/s, the friction factor of the pipe 0.008, and the pump and motor efficiencies are 85 % and 92 %, respectively. Assume height of pump/motor negliglible. Q1. Calculate the gauge pressure at the pump's inlet (at C) (kN/m2) Q2. Calculate the gauge pressure at the pump's outlet (at D) (kN/m2) Q3. Calculate input power to motor (kW)

A large, open-topped water tank is being filled from above by a 1.0-cm-diameter hose. The water in the hose has a uniform speed of 11 cm/s. Meanwhile, the tank springs a leak at the bottom. The hole has a diameter of 0.70 cm. Determine the equilibrium level heq of the water in the tank, O measured relative to the bottom, if water continues flowing into the tank at the same rate. heq 1.26 X10-3 Incorrect m
