Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

A firm in Manila operates a Diesel Electric Plant to supply its electric energy requirements. During a 2 hour period, the plant consumed 250 gallons of fuel at 80°F and produced 2900 kW-hrs. Industrial fuel is used at 30°API and was purchased at P30/li at 60°F. Determine the overall thermal efficiency of the plant in percent?.
Can the combined turbine–generator efficiency be greater than either the turbine efficiency or the generator efficiency? Explain.
The utility company is selling electric power for $0.06/kWh at night, and $0.13/kWh for power produced in the day. Company WaterCO builds a large reservoir 50m above lake level to pump water from the lake to the reservoir at night, and then letting the water flow from the reservoir back into the lake during the day; creating power as a pump-motor operation and a turbine-generator for reverse flow. Here, the water flow rate of 2 m3/s is used in either direction and the irreversible head loss of the piping system is 4m. The combined pump-motor and turbine-generator efficiencies are 80% each. If the system operates for 10 hours each in the pump and turbine modes during a normal day, what is the potential revenue this pump-turbine system can generate per year?
