Why Is Carnot Cycle Impractical? Carnot cycles are not encountered in reality since achieving isothermal heat transfer is very difficult (needs very large heat exchangers and long time). Also process 3-4 requires a pump or compressor that can handle two phase mixture (liquid and vapor) which is impractical. Why is Carnot cycle not possible? In
Why Efficiency Of Reversible Engine Is Greater Than Irreversible Engine? The efficiency of an irreversible heat engine is always less than the efficiency of a reversible one operating between same two thermal reservoirs. … The efficiencies of all reversible heat engines operating between the same two thermal reservoirs are the same. Are reversible engines more
Which Of The Following Is An Example Of Irreversible Process? Some examples of irreversible processes are electric current flow through a conductor with a resistance, magnetization or polarization with hysteresis, inelastic deformation, fluid flow with shock wave, and mixing of fluid with different temperatures, pressures, and/or compositions. Which one of the following is an example
On Which Condition Work Done In A Cyclic Process Becomes Zero? Solution. The change in energy in a cyclic process is zero, since the initial and final states are the same. The work done and the quantity of heat gained in such a process are therefore the same with opposite signs (R = –Q). In
What Are The Conditions For A Process To Be Reversible? The substance undergoing a reversible change must at all instances be in thermodynamic equilibrium with its surroundings. … All the processes taking place in the cycle of operation must be infinitely slow. There should be a complete absence of frictional forces. What are the requirements
