Propionic acid is diffusing through a 4.0 mm stagnant thick film of deuterium oxide (heavy water) at 298 K. At one end of the film, the concentration of propionic acid is 16.8 wt% and the solution density is rho1 = 1072.8 kg/m^3 . At the other end of the film the concentration of propionic acid is 6.8 wt% and rho2 = 1088.1 kg/m^3 . The diffusivity of propionic acid in deuterium oxide is 1.01 x 10^-9 m^2 /s.
a. Calculate the steady-state flux Na.
b. Assuming the binary mixture is a dilute solution of propionic acid, calculate the steady-state flux NA.
c. Compare NA from part (a) and (b). What can you conclude about the system from this?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
