A pumped storage power plant with a head of 150 m, with a flow rate of 6 cms for power generation and pumping, and continuous operation for 8 hours each time. Try to find (1) the power output during power generation and the total daily power generation; (2) pumping water Hourly power and total daily power demand; (3) Pumped storage power plant efficiency; (4) Adjust the pool capacity? Assuming that the water loss is 8% of the total drop, the combined efficiency of the turbine and generator is 85%, and the efficiency of the pump is 65%.
A water tank is attached to a piping system with a sharp edge inlet (KL=0.5). Determine the velocity of the outlet water if the system has two elbow pipes (KL=1.5), the length of the entire system is 10m, the diameter is 1.5cm, the friction factor is 0.002 and the height between the water and the outlet are 5m.
The drinking water to a village is supplied from a reservoir which is 475 m above and 25 km away from the village. The water is transported from the reservoir to an open-top storage tank in the village via a circular pipe with a diameter of 18 cm and a roughness of 0.15 mm. The population of the village is 1500 people. There are two valves (K=2) and five 90° elbows (K=1.5) along the pipe. Assuming that an average person in the village consumes 225 L/day, determine the power (kW) of the pump needed to transter the water from the reservoir to the storage tank. You can take the density and viscosity of water as 1000 kg/m and 0.001 kg/m s, respectively, and you can neglect the inlet and exit losses and the kinetic energy correction factor effects.
I need help on this question: According to the question: a) If the pipe connected to the pump inlet has a diameter of 24 mm with length (LCP) of 5 m and Darcy friction factor of 0.03, what would be the actual head rise across the pump for a case where the pump outlet pressure is 200 kPa? The difference in height between pump inlet and outlet is 0.25 m, the tank exit is sharp-edged, and the water level in the tank to the tank exit pipe (HWL) is 2 m. Also, consider that the flow velocity inside the tank is negligible. The value of the actual head rise across the pump is = ? b) What would be the pump motor power if the efficiency is 60%? The value of the pump motor power is = ?
A 70% efficient water pump is use to pump water to a tank which is 30 m above, the water pump is operated at 240-V, 10-A. The pipe has 5-cm-diameter at inlet and 4-cm-diameter at outlet.
