At 1 kg copper part, initially a 500K is plunged into a tank containing 4 kg of liquid water initially at 250K. The copper part and water can be modeled as incompressible with specific heat 0.4 KJ/ kgK and 4 KJ/kgK, respectively. For their copper parts and water as the system. Ignore the heat transfer between the system not in surroundings. Write the energy balance equation for the full system including both copper parts and water part. Define the final equilibrium temperature in K for the system Wright the entropy balance equation and deletes terms are not necessary calculate the amount of entropy produced within the tank in KJ/K Due to part d this process is ________________? - internally reversible

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.
