A hydroelectric plant with a power-generation capacity of 12 MW costs $20 million to install. The fixed charge rate is 7.0 percent, the annual operation and maintenance cost is assumed to be 1.0 percent of the initial cost and the levelized replacement cost is averaged over an expected 40-year lifetime. If the capacity factor for this plant is 0.38, what is the cost of energy?

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
