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.

Describe the equilibrium condition in terms of the entropy changes of a system and its surroundings. What does this de-scription mean about the entropy change of the universe?
A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40°C and an initial volume of 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. The process is then maintained by allowing the volume to change while the pressure is kept constant. At the end of this process, the temperature reaches 50°C. Assuming the state changes as if they are balanced,calculate;a) The mass of R-134a refrigerant in the system,b) The amount of heat transferred during the fixed volume process,c) The amount of heat transferred during constant pressure operation.d) Show the state changes on the P-v diagram.
Need help on this one. A cylinder having an initial volume of 3 m3 contains 0.1 kg of water at 40°C. The water is then compressed in an isothermal quasi-equilibrium process until 71% of the mass is in liquid phase. Assuming that water behaves as an ideal gas during the first step of the process until the 2nd state is just reached, (a) Draw the t-v and p-v diagrams, (b) calculate the total work done (kJ) splitting the process into two steps, superheated vapor to saturated vapor to saturated liquid vapor. (c) determine the internal energy u (kJ/kg) of water at final state.
Two rigid tanks A and B are connected by a valve. Tank A contains 0.6 of water at 550 kPa and 43 percent quality. Tank B contains 0.81 of water at 200 kPa and 700 oC. The valve is now opened and the two tanks eventually come to the same state and reach thermal equilibrium with the surroundings at 35 oC. Calculate the followings: a) The final pressure in the system (kPa); b) the amount of heat transfer (kJ). Submit your solution by adding (a) + (b) = View solution Format answer : 8599.6782
A piston-cylinder device initially contains 0.4 m^3 of saturated water vapor at a pressure of 200 kPa. At this time, a linear spring (K = 150 N/m) is touching the piston, but exerts no force upon it. Heat is now transferred to the water vapor for 30 minutes through a resistive heater having a current of 10 amperes. The pressure and volume rise to 300 kPa and 0.6 m^3 while the system lost 10 kJ of heat during this process. Determine the voltage of the resistive heater and draw the provess on a P-v diagram with respect to saturation lines. Show detailed calculations and specify any required values found on thermodynamic tables.
A 100L tank initially contains water at 100kPa and a quality of 1%. Heat is transferred to the water, raising the temperature and pressure. At a pressure of 3 MPa, a safety valve opens and saturated vapor at 3 MPa flows out. The process continues, maintaining 3 MPa inside until the quality in the tank is 90% and then stops. Determine the total mass of water that flowed out and the total heat transfer.
R-134a is a refrigerant, which is used inside of refrigerators and air conditioners. You can buy canisters of this as a compressed liquid, which can be used to recharge a leaky air conditioner. The canister initially contains 0.539 kg of R-134a at room temperature (25 °C). For simplicity, let's assume that the R-134a is initially saturated liquid. You use this canister to recharge an air conditioner, until the canister has half of its original mass remaining. The canister is upright with the exit on the top of the canister, so the exit flow is saturated vapor. In order to maintain the temperature at 25 °C, how much heat must be supplied to the canister? Note that this is why compressed liquid/gas canisters feel cold when you use them – they require heat - input to maintain constant T.
Question 1 (a) In the thermodynamic laboratory, student Ali prepared a piston-cylinder device which contains refrigerant-134a at 1000 kPa and 50°C. The mass of the refrigerant is 6 kg.

Show the process on T-v diagram and determine the heat loss from the system.
