A plant requires 900 mol/hr*mof tower cross section to cool water from 45 C to 25 C. The temperature of the entering air is 32 C with wet-bulb temperature of 15 C. a. Plot the equilibrium curve in EXCEL software. i. For temperature 0-60 C with interval of 5, determine values of humidity, H (kg water/kg dry air), at saturation (from psychrometric chart). ii. Compute for Hy (J/mol dry air) for each value of temperature and humidity. Provide a table. Careful with conversion. iii. Graph the Hy vs temperature to obtain the equilibrium curve. b. Determine the minimum gas rate, Gmin, graphically. Usually, at the minimum gas rate, the exit gas will be in equilibrium with the inlet water. c. Sketch the actual operating line if the gas flow rate is twice the minimum gas rate
