Answer the following statement true (T) or false (F)
Your chemical plant manufactures a chemical which has a constant heat capacity of CV = 3R, is in the gas phase at all process conditions, and can be modeled as an ideal gas as long as the pressure is below 5 atm. There is a point in the process where the compound is at P=2 atm and T=400 K, and must undergo a reduction in pressure to P=1 atm. Currently, this is done by a steady-state adiabatic throttling valve. Your boss has asked you to examine the possibility of replacing this valve with a turbine, so that some useful work can be obtained from the necessary drop in pressure. The efficiency of the turbine would be 75%.
A) In the current process, what is the temperature of the gas leaving the valve? B) How much work would the turbine produce for each mole of entering gas? C) What would be the actual temperature of the gas leaving the turbine?
