Steam assisted gravity drainage (SAGD) is used to mobilize and recover bitumen. A compressor at sea level is used to compress 660 SCMM of steam from 58 psig and 752F to 290 psia and 797F. The pipes to and from the compressor are 10 inch ID. (a) If the compressor operates adiabatically, how much power (kW) does the compressor transfer to the steam through shaft work? (b) At the conditions of 1000 bar and 797F, calculate the specific volume (m3/kg) of steam using the ideal gas law, and then with the compressibility factor (z), and compare to the value obtained using the steam tables. Which value is the most accurate?
