(20 points) Cyclohexane is pumped into a 15,000 gal vessel at a rate of 45.0 kg/min. The tank was evacuated before any cyclohexane was added and is held at 50.0C throughout the filling process. After 3.0 hours of filling, what is the pressure in the tank, what phases are present, what is the volume of each phase, and how much cyclohexane (in kg) is in each phase? Molecular weight: 84.16 g/mol Vapor Pressure at 50C: 36.17 kPa Melting point: 6.54 C Liquid density at 50C: 0.750 g/cm3 Vapor density can be determined from the ideal gas equation Normal Boiling Point: 80.7C Critical Temperature: 281C
