4. The enthalpy H may be written as a function of temperature T and pressure P. If we have a system whose composition remains constant and using Maxwell's equations and the total differential, we...
Because (∂H/∂P)T =−CPμJ−T, the change in enthalpy of a gas expanded at constant temperature can be calculated. To do so, the functional dependence of μJ−T on P must be known. Part A Treating Ar as a van der Waals gas, calculate ΔH when 1 mole of Ar is expanded from 329 bar to 1.68 bar at 375 K. Assume that μJ−T is independent of pressure and is given by μJ−T=[(2a/RT)−b]/CP,m, and CP,m=5/2R for Ar. The van der Waals parameters a...
(25 pts) We have a tank of volume V which contains an ideal gas at constant temperature T and initial pressure Po. There is a small hole in the tank and gas leaks out at a velocity of (RT)5, We can use a molar density 1. Recall that mols in tanke ρν and molar rate out-pud where u-velocity and A - area of hole. Derive the differential equation for P vs t (hint it's a simple exponential) a. drop in...
