Water at 65°F and 20 psia is mixed steadily with saturated water vapor at 20 psia in an insulated chamber. Assume the chamber operates isobarically at 20 psia and the kinetic and potential energies are negligible. If the cooler water is mixed with the hotter vapor with a mixing ratio of 0.4 (parts cold water per 1 part vapor), what is the quality of the exit stream?

A 3.1 kg mass of saturated liquid-vapor mixture of water is contained within a closed system in a vertically arranged piston-cylinder device at a pressure of P1. Initially, 1.1067 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches P2. Heat transfer continues until the total volume increases by 19 percent. Consider Case #7 from Table 1: Table 1: Case # along with the list of pressures P, and P2 Case # P1 (kPa) P2 (kPa) 100 300 150 300 3 200 500 4 250 500 300 500 350 700 400 700 8. 450 700 (a) show the process on a P-v diagram in reference to the saturation lines, (b) determine the initial and final temperatures, (c) determine the mass of liquid water when the piston first starts moving, and (d) determine the work done during this process.

Suppose that 1.73 grams of X (MW 35.05) are dissolved in 639 mL of water, and the water temperature changes from 29.29°C to 28.39°C.

Assume the specific heat of water is 4.2 J/(g.°C) and the density of water is 1.0 g/mL. %3D Calculate the enthalpy of dissolution of X in kJ/mol. Report your answer to three decimal places.
A closed container with constant volume insulated against heat is divided into two compartments by a steel curtain. Achamber contains 2 kg of water at 800 kPa pressure and 80 oC temperature. The other compartment isis empty (vacuum). Then the steel curtain is removed and the water fills the whole container. EndIn the equilibrium state, since the pressure of the water is 10 kPa, the final temperature of the water andCalculate the volume of the tank.
Consider a pure liquid in equilibrium with its vapor at constant temperature. a) write an expression relating the chemical potential of the liquid, u(l), and vapor, u(g). b) express u(g) in terms of the vapor pressure of the pure liquid, P.
A mixture of 87.3 mole % methanol and 12.7 mole % isopropyl alcohol is vaporized at 101.325 kPa (absolute) until 900 moles of vapor and 100 moles of liquid in equilibrium with each other are produced. This occurs in a single-stage system and the vapor and liquid are kept in contact until equilibrium is achieved. Calculate the composition of the vapor and liquid. Note: Assume the system exhibits ideal behavior (which it mostly does), e.g. Raoult’s Law applies and an Antoine’s Vapor Pressure correlation is a sufficiently accurate model of component vapor pressure.

A 1 cm diameter spherical pellet of a strongly basic oxide is held at the center of a closed vessel of 5-liter volume. Initially the vessel is evacuated and then filled with an equimolar mixture of H₂S and N₂ at 25 °C and 1 atm total pressure. As the molecules of H₂S reach the surface of the pellet, they get absorbed instantaneously so that the concentration of H₂S at the surface remains zero at all time. Diffusion of H₂S occurs through a stagnant film of estimated thickness of 4 mm surrounding the pellet. The bulk of the gas may be assumed to have a uniform composition at any time. Calculate the time of absorption of 95% of H₂S in nitrogen is 1.73x10 m²/s at this temperature and 1 atm pressure. Closed vessel, volume = 5 litres Mixture of H₂S (4) and N₂ (B) H₂S diffuses through N₂ H₂S. Absorbent sphere Total pressure, P=0.5+PAD Gas-film of thickness, 8=4 mm
