Problem 3.30:
1 mol of liquid hexane at 10 bar, 25 °C, is mixed adiabatically and under constant pressure with hexane vapor at 180 °C. Determine the moles of the vapor that must be mixed with the liquid in order to produce a final state that consists of a vapor-liquid mixture with 75% (by mass) liquid. You may use the data given in problem 3.29. Problem 3.31:
Methanol at 25 °C, 8 bar is heated under constant P in closed system. a) Determine the amount of heat to produce 95% vapor b) Determine the final state if Q = 32000 J/mol c) Determine the final state if Q = 52000 J/mol Additional data:
