25. 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 water's 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 with a volumetric flow rate of 65 m'ls to a turbine, where electric power is generated. The total irreversible head los in the piping system from point 1 to point 2 (excluding the turbine unit) is determined to be 95 m. The pressure difference due to elevation cannot...

QUESTION 4 points Save Answer You are the sustainability coordinator for a company and are evaluating green energy options. You get a company to lend you a biomass-to- energy (B2E) system for a 30-day trial. The B2E system is 34% efficient and you need 1.5 MW of power to meet the company's energy needs. You also plan to use the waste heat for hot water, which is needed at a flow rate of 0.02 m3/s. A neighboring company produces waste...
