1.95', Hydrodynamio fow through a porous diaphragm Consider the hydrodonamic flow of nitrosen at 400K through the porous Aixphragm described in Example 1.24. It is desined to achieve a superfidal gas velveity through the diaphragm of 0.28kg of NR/m2s by increasing the upatream prosure while maintaining the downstream pressure constant at 0.1atm. Calculate the upstream pressure required. Answer: 13.64kPa 1.20*. Oxygen diffusion in water; Hayduk and Minhas correlation Bstimate the diffusion coefficient of oxygen in liquid water at 298K. Use the Hayduk and Minhas correlation for solutes in aqueous solutions. At this temperature, the viscosity of water is 0.9cP. The critical volume of oxygen is 73.4cm2/mol. The experimental value of this diffusivity was reported as 2.1105cm2/s (Cussler, 19972
