In the condenser of a power plant, energy is discharged by heat transfer at a rate of 836 MW to cooling water that exits the condenser at 408C into a cooling tower. Cooled water at 208C is returned to the condenser. Atmospheric air enters the tower at 258C, 1 atm, 35% relative humidity. Moist air exits at 358C, 1 atm, 90% relative humidity. Makeup water is supplied at 208C. For operation at steady state, determine the mass flow rate, in kg/s, of (a) the entering atmospheric air. (b) the makeup water. Ignore kinetic and potential energy effects.
HOMEWORK The following general comments: 1. Companies (or research journals) have report formats that every engineer must follow, irrelevant of their individuality. 2. Employees do not give their boss the scratch paper, but a final neat ORGANIZED document. THINK OF ME AS YOUR BOSS 1. I have a report format that the employees of my company will follow. 2. Homework turned in will be a neat, organized document that flows from left to right and from top to bottom. a. You would not turn in your first draft in English composition, do not do it while in this Department. b. Use a ruler if you must! Architecture students spend hours on their drawings after they worked out the final design
