In some graphs of the Isenthalpic curves (not the one above) I've seen that the isenthalpic curves touch the ordinate axis to give a positive temperature value and a zero pressure value on the exit side of the throttle valve. Is this possible?
This is a graph obtained during throttling process by keeping pressure and temperature at the inlet of the valve fixed and varying them at the outlet to get different isenthalpic curves for different inlet pressures and temperatures.
Is it true that the sudden change in temperature of this...
