The Joule-Thomson coefficient measures the change of temperature of a gas with respect to the change in pressure at constant enthalpy: B. (6 pt.) Starting with dH = OH OP MJT A. (3 pt.) Assuming that the Joule-Thomson coefficient for gaseous nitrogen can be taken as a constant and is given by 0.15K bar, what is the temperature change upon a pressure drop of 100bar? T dP+ (hint: set iso-entalpic dH=0) C. (4 pt.) Use the result in B to show that OT ap D. (5 pt.) We have shown in Chapter 8 that ƏH ar ace ap ƏH H P dT, show that H =-Hл acp ar = =V-T -CP P 7 (27); " av 1 OH OP Cp ÔμT OT . Use this result in the OP T expression (B) to show that [-] E. (3 pt.) Use the results above to find the values of Mr for an ideal gas. F. (4 pt.) Use the result in D to find an expression for for a gas that satisfies the following equation of state: P(V-nb)=nRT, in terms of b and Cp.
