An electric power generating plant has an output of 100 MW. The boiler of the plant operates at 300 degrees celsius. The condenser operates at 40 degrees celsius.
a. At what rate (joules per hour) must heat be supplied to the boiler?
b. The condenser is cooled by water, which may undergo a temperature rise of no more than 10 degrees celsius. What volume of cooling water in cubic meters per hour is required to operate the plant?
c. The boiler temperature is to be raised to 540 degrees celsius, but the condensed temperature and electric output will remain the same. Will the cooling water requirement be increased, decreased or remain the same?

A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 300?C . The steam spins a turbine, which produces 900MW of electric power, then the steam is condensed and the water is cooled to 25?C before starting the cycle again. A) What is the maximum possible thermal efficiency of the power plant? Express your answer using two significant figures. B) Cooling...

In a steam power plant which has a net power output of 45 MW, steam is supplied at 10 MPa and 500°C. The steam is reheated after passing through high pressure turbine to its original temperature at a pressure of 1 MPa. Then the steam expanded to condenser pressure. The condenser pressure is 5 kPa. Show the cycle on a T-s diagram with respect to saturation lines, and determine; (i) the thermal efficiency of the cycle; and (ii) the mass...

A steam power plant operates with a high pressure of 4 MPa and has a boiler exit at 600C recieving heat from 700C reservoir. The ambient air at 20C provides cooling to maintain the water/vapor mixture in the condenser at 60C. All components are ideal (reversible) except the turbine which has an efficientcy 92% of a reversible, isentropic process. other than that the irreversibility of the turbine, the power plant can be considered as a Rankine cycle.

Consider a 1.4 MW power plant (this is the useful output in the form of electric energy) that operates between 30∘C and 450∘C at 65% of the Carnot efficiency. This is enough electric energy for about 750 homes. One way to use energy more efficiently would be to use the 30∘C "waste" energy to heat the homes rather than releasing that heat energy into the environment. This is called cogeneration, and it is used in some parts of Europe but...

Atlantic Power, a large electric power utility, has built a modern nuclear power plant. This plant discharges waste water that is allowed to flow into the Atlantic Ocean. Environment Canada has ordered that the waste water temperature must be less than 15 degrees Celsius on average. The company would like to determine whether the population mean waste water temperature is indeed less than 15 degrees. In the real world, hundreds of temperature readings would be gathered each day; in this...
