3. In a hydroelectric power plant, water flows from an elevation of 240 ft to a turbine, where electric power is generated. For an overall turbine-generator efficiency of 83 percent, determine the minimum flow rate required to generate 100 kW of electricity. Determine the flow rate of water if the irreversible head loss of the piping system between the free surfaces of the source and the sink is 36 ft.

Step 1
The potential energy (PE) can be calculated using the formula: PE = m*g*h where: m is the mass of the water, g is the acceleration due to gravity (32.2 ft/s^2), and h is the height (240 ft). However, we need to find the flow rate (Q), not the mass. The flow Show more…

In a hydroelectric power plant, $65 \mathrm{~m}^{3} / \mathrm{s}$ of water flows from an elevation of $90 \mathrm{~m}$ to a turbine, where electric power is generated. The overall efficiency of the turbine-generator is 84 percent. Disregarding frictional losses in piping, estimate the electric power output of this plant.

Water flows from a reservoir at the rate of $3000 \mathrm{~kg} / \mathrm{min}$, to a turbine $120 \mathrm{~m}$ below. If the efficiency of the turbine is 80 percent, compute the power output of the turbine. Neglect friction in the pipe and the small KE of the water leaving the turbine. Don't forget that it's only 80 percent efficient.
