An electrical power plant has an overall efficiency of 15%. The plant is delivered 150MW of  power to a city, and turbines use coal as fuel. The burning coal produces steam at 190 0C,  which drives the turbines. The steam is then condensed at 25 0C by passing it through cooling  coils in contact with river water. a) How many metric tons of coal does the plant consume each day? b) What is the total cost of the fuel per year if the delivered price 10 USD per metric  ton? c) If the river water is delivered at 20 0C, at what minimum rate must it flow over  the cooling coils in order to that its temperature not exceeds 25 0C? Heat of  combustion of coal is 33 kJ/g

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
