The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. Calculate the number of kilograms of hydrogen that pass per hour through a 5.5-mm-thick sheet of palladium having an area of 0.45 m2 at 500°C. Assume a diffusion coefficient of 5.0 × 10-8 m2/s, that the concentrations at the high- and low-pressure sides of the plates are 2.3 and 0.43 kg/m3 of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.

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.
