Unformatted text preview: independent C p = 7R/2 , and the average molecular weight of air is 28.8. 3. Steam at 500 bar and 500 º C undergoes a throttling expansion to 1 bar. What will be the temperature of the team after the expansion? What would be the downstream temperature if the steam were replaced by an ideal gas, C p /R = 7/2 ? 4. N.B. Vargaftik (1975) lists the following experimental values for the specific volume of isobutene at 175 o C. Compute theoretical values and their percent deviations from experiment by (a) the generalized charts (b) the Peng-Robinson equation P (atm) 10 20 35 70 V (cm 3 /g) 60.7 27.79 13.36 3.818...
