Clausius inequality - thermodynamics:
Whenever closed system undergoes cyclic process, cyclic integralis less than zero (that is negative) for an irreversible cyclic process and equal to zero for a reversible cyclic process.
The efficiency of reversible H.E. operating within temperature T1 & T2 can be given by:
or for a reversible engine. .......(i)
Now efficiency of irreversible H.E. operating within same temperature limit T1 and T2 can be given by
Combining equation (i) and (ii); we get d ≤ 0 The equation for irreversible cyclic process can be written as: + 1 = 0 I = Amount of irreversibility of cyclic process.
Compare Rankine cycle with Carnot cycle: Sol.: Rankine cycle without superheat: 1 - A - 2 - 3 - 4 - 1. Rankine cycle with superheat : 1 - A - 2 - 2′ -3′ - 4 - 1.
Diode: It allows the current to flow in one direction only and offers infinite resistance in other direction. It rectifies the alternating current that is why we call it rectifie
