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.

Steam (water vapor) enters a stainless steel tube with inner diameter 4cm at 300°C and 60 bar absolute pressure, with a velocity of 8.00 m/s. The steam exits the tube at 300°C and 40 bar absolute pressure. a. Assuming the water vapor behaves as an ideal gas, calculate the steam mass flow rate and the change in kinetic energy (in Watts). b. Using the specific volume values from table B.7, calculate the steam mass flow rate and the change in kinetic energy (in Watts).
The feed to a compressor is superheated steam at 310°C and 40 bar. It enters the compressor at a velocity of 17 m/s. The pipe inlet inside diameter is 0.25 m. The discharging pipe, after the compressor, has a smaller inside diameter and the discharge velocity is 120 m/s. The exit of the compressor is superheated steam at 350°C and 85 bar absolute. Heat loss from the compressor to the surroundings is 3 kW. Determine the compressor horsepower
Steam (H2O) enters a turbine at 35 m/s and specific enthalpy of 3500 kJ/kg. Thesteam leaves the turbine as a mixture of vapor and liquid having a velocity of 60m/s and a specific enthalpy of 2400 kJ/kg. If the flow through the turbine is steady,adiabatic, and changes in elevation are negligible, calculate the work output per unitmass (kJ/kg) for the turbine.
