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.

During a steady-flow process 5,000 kg/h of fluid passes through an apparatus in which the exit pipe is 2 m below the level of the inlet connection. Penitent data regarding the working fluid are pressure decreases from 700 to 140 kPa; velocity increases from 60 to 360 m/s; internal energy decreases by 50 kJ/kg; specific volume increases from 0.06 to 0.36 m3 /kg. If the heat radiated from the apparatus is 10,000 kJ/h, calculate the work exchanged with the surroundings in kW. Indicate the direction of the work.

A Carnot engine uses ethylene as its medium. The volumes at the beginning and end of the reversible adiabatic expansion process are 0.1 ft^3 and 2.5 ft^3, respectively. Fund the thermal efficiency.
A high pressure steam turbine receives steam from a boiler under unknown conditions. The isentropic efficiency of the turbine is 75% and it produces 1MW. The high pressure turbine outlet steam is at 1.4 MPa under saturated conditions. The high pressure turbine exhaust supplies 1000kg/min for use in a process, in addition to an unknown flow of steam that follows the path, being supplied to a low pressure turbine that produces 820kW when it releases steam at 10kPa and has a isentropic efficiency of 60%. The steam that was used for the process (out of the high pressure turbine) after being used, returns to the cycle taken by the pump, which also takes the outlet of the condenser and does so at 10kPa as saturated liquid. Consider the efficiency of the pump equal to 90%. Determine: A) the mass flow through the boiler B) the pressure and temperature at the outlet of the boiler C) the thermal efficiency of the cycle
