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.

Question

enclosing 0.5 kg of steam at 0.4 MPa. Calculate the amount of heat

A piece of steel of mass 0.9 kg has a temperature of 95°C. It is immersed in a copper calorimeter which contains 0.45 kg of water at a temperature of 20°C. The final temperature of the calorimeter system, after cooling correction had been taken into account, became 32°C. If the specific heat capacity of steel is 480 J/kgK and that of copper is 394 J/kgK, determine the water equivalent of the calorimeter system.
Water enclosed in a rigid tank is heated from 120°C to 250°C. The pressure is high enough that the water remains subcooled (compressed) liquid during the process. Determine the thermal energy needed for the process (in kJ) if the mass of water is 8 kg. You can use water property tables or the incompressible substance assumption.
A rigid tank of volume 2.5 m3 contains 15 kg of moist water vapor at 75°C. The water is then slowly heated.

Also describe the process on a T-V diagram with respect to the saturation lines.
The water was heated up until the temperature is 200C.
