During Throttling Process Enthalpy?

Throttling Process Thermodynamics - Thermodynamics
A throttling process is defined as a process in which there is no change in enthalpy from state one to state two, h1 = h2; no work is done, W = 0; and the process is adiabatic, Q = 0.

Why the enthalpy is constant during the throttling process?

A throttling process is a thermodynamic process, in which the enthalpy of the gas or medium remains constant (h = const). ... During the throttling process no work is done by or on the system (dW = 0), and usually there is no heat tranfer (adiabatic) from or into the system (dQ = 0).

What happens during throttling process?

The throttling effect is to reduce the inlet pressure by a constant enthalpy process (represented by horizontal line AB). The result is a loss in entropy and also a slight fall in temperature with some reduction in the available heat drop. This accounts for a small loss in efficiency.
