Throttling process - thermodynamics, Mechanical Engineering

Assignment Help:

Throttling Process:

The expansion of gas through an orifice or partly opened valve is called as throttling.

q1-2 = 0 and w1-2  = 0

Now             2112_Throttling Process.png

The throttling process is constant enthalpy process.

If readings of pressure and temperature of Joule

Thompson porous plug experiments are plotted,

h1 = h2 = h3  = h4  = h5

The slope of constant enthalpy curve is called as Joule

Thompson coefficient. p = dT/dP
