A power plant generates 150 MW of electrical power. It uses a supply of 1000 MW from a geothermal source and rejects energy to the atmosphere. Find the power to the air and how much air should be flowed to the cooling tower (kg/s) if its temperature cannot be increased more than 10°C. Finally, if you assume the power plant operates on a Carnot Cycle and the atmosphere is 20°C (assume the heat rejection occurs at constant temperature), what is the temperature of the geothermal source?
A project that will cost $750,000 will require payments as certain milestones are met. The initial payment is $50,000. When 30% of the work is complete an additional payment of $200,000 is due. When 70% of the work is complete another payment of $..
