Problem 4. A nuclear power station produces 800 MW of useful energy, with an efficiency of 32%. Calculate the minimum rate at which cooling water must be pumped through the condensers, if the maximum cooling water temperature rise is 8.3°C. Assume no heat is lost to the atmosphere directly from the system, i.e., all waste heat is absorbed by the cooling water. Give your answer in m³/s (note 1 kW = 1 kJ/s). Assuming the plant is designed with five identical pipes in parallel to carry this cooling water, calculate the diameter of each pipe (in in meters) if the water velocity is 1.8 m/s.

In the system shown in the figure, saturated liquid water at 12 MPa pressure enters the boiler at a flow rate of 45 kg / h. Heat is transferred from a heat source at 650 ° C to the water in the boiler at constant pressure, and superheated steam at 450 ° C temperature is obtained. The steam in the form of superheated steam then expands adiabatically in the turbine and comes out as saturated steam at 50 kPa pressure. a) Show the operations on the T (° C) -s (kJ / kgK) diagram. b) Find the isentropic efficiency and power of the steam turbine. c) Find the total entropy generation by calculating the entropy productions in the boiler and the turbine.

In a fossil fuel power plant the chemical energy stored in fossil fuels such as coal, fuel oil, natural gas or oil shale and oxygen of the air converted successively into thermal energy, mechanical energy and, finally, electrical energy. now assume that a coal-fired plant with a capacity of 100 MW uses coal as an energy source to produce heat which later converted to electrical energy with 60% efficiency (40% is lost as heat). The total heat of coal is given 6000 kcal/kg. The combustion temperature for steam is 100-celsius degrees. The cooling water is provided from a river with an ambient temperature of 25 Celcius degrees. The power plant operates 24 hours per day. Based on the information given in the problem, Calculate; a) How many tons of coal should be used in this power plant? b) What is the Daily amount of DI water for the production of steam? c) What is the Daily amount of cooling water for condensation?
