The entering water stream is pure water. The total mass flow rate of the entering gas stream containing NW-wt% ammonia is h Ibm/hour. The removal percentage of ammonia from the entering gas stream is RN % by absorbing ammonia into water. The feed rate of water to the absorber is WR times the minimum feed rate of water to the absorber. The tray spacing is SP inch, the fraction of a cross-sectional area of the absorber is FA, and the percentage of flooding velocity is FL %. Assume that temperature is constant at 10C, water is non-volatile, and air does not dissolve in water. Equilibrium data are available in Table 12-3. Table 1.
