2. The ideal gas mixture contains A and B components, the concentration of the A component is, flowing through the top of the circular tube (the height of the circular tube XA2 z), the circular tube contains fluid A and its liquid level maintains a height of Z1, assuming that the A component is in the gas phase equilibrium concentration of Z1, and B is insoluble in liquid A, constant temperature, constant pressure, under operation, then XA14 a. Performed in a steady state- al. What is the evaporation rate of Moore per unit area of liquid level? a2. As diffusion progresses, the liquid level slowly decreases. It is known that the starting t = 0, the liquid level height is zo when the liquid level drops to ZF takes a few times
