If a process 1 – 2 undergoes a throttling. Which of the following represents the process 1 – 2?

If a process 1 – 2 undergoes a throttling. Which of the following represents the process 1 – 2? Correct Answer H1 = H2

In a throttling process, no heat is absorbed or rejected by the liquid refrigerant. It is also called as an isenthalpic process, in which change in internal energy and flow work remains the same. Enthalpies remain same, so H1 = H2 represents throttling. T1 = T2 is the isothermal process. S1 = S2 is an isentropic process. P1 = P2 is an isobaric process.
