Step 1
5 * mass flow rate * velocity^2 Given: mass flow rate = 50 kg/s velocity = 32 m/s Input power = 0.5 * 50 * 32^2 Input power = 0.5 * 50 * 1024 Input power = 25600 W = 25.6 kW ** Show more…

In a hydroelectric dam, water falls 25 m and then spins a turbine to generate electricity. (a) What is ∆U of 1.0 kg of water? (b) Suppose the dam is 80% efficient at converting the waters potential energy to electrical energy. How many kilograms of water must pass through the turbines each second to generate 50 MW of electricity? This is a typical value for a small hydroelectric dam.

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.
The electric output of a power plant is 750 MW. Cooling water flows through the power plant at the rate $1.0 \times 10^{8} \mathrm{L} / \mathrm{hr} .$ The cooling water enters the plant at $16^{\circ} \mathrm{C}$ and exits at $27^{\circ} \mathrm{C}$ What is the power plant's thermal efficiency?
