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.

Which statement is fals? O In an isolated system of many particles in equilibrium a microstate with all particles having the same energy is more likely than a microstate with 1/ of the particles having the same energy and 1/2 of the particles having zero energy. When water freezes its entropy decreases. O The coefficient of performance for a heat pump is the ratio of the energy delivered at the higher temperature to the work put into the system. O The coefficient of performance for a refrigerator is the ratio of the energy removed at the lower temperature to the work put into the system. O The total entropy of a closed system is always increasing is one way of stating the second law of thermodynamics.

Q1: An engineer claimed that his device produces two streams of 1 am air (outlet 1) and 1.5 atm (outlet 2) at temperatures of 460 °R and 635 °R, respectively, if he enters 530 °R of the air at 5.1 atm. If the ratio of outlet 2 to outlet 1 is 0.6, justify the engineer's claim. Assume ideal gas process with a constant heat capacity of 0.24 Btu/lb.°R.
a.Draw a schematic diagram with labels of states of a substance; b.For uniformity purposes, assign STATE 1 at the inlet of a high-pressure turbine. The states must be arranged in a chronological order; c.Plot each cycle in a t-s diagram with the states consistent to the states assignment in the schematic diagram; d.Show a detailed solution. Consider a regenerative vapor power cycle with a single open feedwater heater. Steam enters the first turbine stage at 12MPa, 500 0C, and expands to 0.3MPa where some steam is extracted and fed to the feedwater heater. The remainder expands through the second-stage turbine and exits at the condenser pressure of 0.01 MPa. Saturated liquid at 0.3 MPa leaves the open feedwater heater. If the net power output of the cycle is 100 MW,and the turbine stages and pumps are isentropic, determine (a) the thermal efficiency, and(b) the mass flow rate of steam entering the first turbine, in kg/h.

Which statement/s are true? Heat is transferred to a system by either an air-sourced Carnot heat pump, an electrical resistance heater or a heat source at temperature marginally higher than the system temperature. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is minimum when heat is added by the air-sourced Carnot heat pump. Heat is transferred to a system either by an 100% efficient electrical resistance heater, or an 100% efficient isothermal heat source. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is zero when heat is added by the isothermal heat source. Heat is transferred to a system by either an air-sourced Carnot heat pump, an electrical resistance heater, or a heat source at temperature marginally higher than the system temperature. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is maximum when heat is added by the electric resistance heater. Heat is transferred to a system by either a…
