Concept explainers

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

3. Please calculate the annual electricity production of a wind farm with 20 turbines. The annual mean wind speed is 7 m/s and diameter of the blades is 20 m. If we assume power consumption of a person is 3,000 kWh, about how many people will this energy support? Annual electricity production (KWh) = K Vm³ At T Where: - - - K = 3.2 (factor based on turbine performance) Vm= annual mean wind speed (m/s) At = swept area of turbine (m2) T = number of turbines Suitable for medium- to large-scale wind turbines (> 200 m2 swept area)
