moody correlation in pipephase gas phase simulation

[halizo]

I dont know if i am doing the rigth question to you guys, if you simulate with pipephase in a gas phase option, the program choose by default: moody correlation pressure drop method, i know that it is the for friction factor, but what is the equation for the pressure drop? is it the isothermal one? or another one.

thanks in advance

The equations are not isothermal, though some equations will assume isothermal while others will or can iterate the equation with allowances for the density change due to a change in temperature due to the JT effect.
