A supply line carries a two-phase liquid-vapor mixture of steam at 20 bars, state 1. A small fraction of the flow in the line is diverted through a throttling calorimeter and exhausted to the atmosphere at 100 kPa. The temperature of the exhaust steam, state 2 is measured as 373 K. Determine (a) the quality at the exit in %

A closed, rigid tank contains a two-phase liquid–vapor mixture of Refrigerant 22 initially at -20°C with a quality of 47.50%. Energy transfer by heat into the tank occurs until the refrigerant is at a final pressure of 6 bar. a) Determine the final temperature, in °C. b) If the final state is in the superheated vapor region, at what temperature, in °C, does the tank contain only saturated vapor?

A two-phase liquid–vapor mixture of Refrigerant 134a is contained in a 2-ft3, cylindrical storage tank at 100 lbf/in.2 Initially, saturated liquid occupies 1.6 ft3. The valve at the top of the tank develops a leak, allowing saturated vapor to escape slowly. Eventually, the volume of the liquid drops to 0.6 ft3. If the pressure in the tank remains constant, determine (a) the mass of refrigerant that has escaped, in lb, and (b) the heat transfer, in Btu. PLEASE USE THE...

1. Obtain the equilibrium mole fractions (liquid and vapor) of a mixture of water, methanol and ethanol at 100 kPa and 70°C. You can assume the mixture is ideal. 2. Create one plot where the equilibrium mole fraction of benzene in the vapor phase is plotted against the equilibrium mole fraction of benzene in the liquid phase for three different pressures (0.2 bar, 0.6 bar and 1 bar). Comment on the effect of pressure on the relative volatility

A mixture of ideal gases A (propane) and B (isopropanol) exist in a vapor-liquid equilibrium in a constant temperature and pressure container. Originally, there is 1 mol A and 1 mol B. The mol fraction of A in the gas phase is 76% and 22% in the liquid phase. Gases A and B start to flow into the system at constant flow rates (at the same constant T and P). The flow rate of A is 3 mol/s. a. Calculate...
