Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

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.
(b) Water is drained from a large reservoir using two horizontal pipes connected in series as shown in Figure Q3(b). The first pipe is 20 m long with 10 cm diameter, while the second pipe is 35 m long and has a 4 cm diameter. The water level in the reservoir is 18 m above the centerline of the pipe. Table Q3(b) shows the friction factor and loss coefficient for each pipe or fittings. Determine the velocity at the second pipe, discharge rate of water and the total head loss. Can you identify the material used in manufacturing the pipe?
