Concept explainers

Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

In a steam turbine system, suppose the value of ∆mH is constant (meaning, inlet and outlet conditions are maintained). From the energy balance equation, Qnet + Wnet = ∆mH + ∆KE + ∆PE or −0.1209 kW − 70 kW = ??̇? + 8.75 kW − 0.0068kW 1. What will happen to Wnet if there was no increase in kinetic energy, will the magnitude of Wnet increase or decrease? What should be the sign of potential energy so that Wnet will increase in magnitude?2. For a turbine system, what should happen to Qnet, ∆KE, and ∆PE to maximize the work done by the turbine? Which factor is the most significant?
The capital cost of a hydro-power station of 50 MW capacity is Rs 1,000 per kW. The annual depreciation charges are 10% of the capital cost. A royalty of Re 1 per kW per year and Re 0·01 per kWh generated is to be paid for using the river water for generation of power. The maximum demand on the power station is 40 MW and annual load factor is 60%. Annual cost of salaries, maintenance charges etc. is Rs 7, 00,000. If 20% of this expense is also chargeable as fixed charges, calculate the generation cost in two part form.
