I need solution to the below problem?
Carbon dioxide is to be expanded adiabatically and reversibly through an insulated nozzle of proper design. The gas will be supplied to nozzle entrance at 8000 psia and 100°F, and at negligible velocity. The discharge pressure with be 500psia. Given that the heat capacity of the gas follows the equation,
Cp = 6.85 – 0.00474T – 7.64 x 10-7 T2 Btu/lbmR
Determine the velocity of the gas at nozzle outlet for the following cases.
1. Carbon dioxide is an ideal gas at pressure up to 800 psia
2. Carbon dioxide is a van der Waals gas at the pressure range of interest such that
P = RT/V-b – a/v2.
With a=924 atmft6/lbmol, b=0.685ft3/lbmol
Universal gas constant = 2 Btu/lbmol/R or 0.7302 atm/lbmol/R
