Repeat Example \(15-10\) but for a bulk gas that is \(40 \mathrm{~mol} \%\) air, \(15 \mathrm{~mol} \% \mathrm{NH}_{3}\), and 45 \(\mathrm{mol} \%\) water. Report \(\mathrm{x}_{\mathrm{NH} 3}, \mathrm{y}_{\mathrm{NH} 3 \text {,surface }}, \mathrm{N}_{\text {water }}\), and \(\mathrm{N}_{\mathrm{NH} 3}\).

Example 15-10

Transcribed Image Text:

A ternary mixture of water (A), ammonia (B), and air (C) is being condensed in a heat exchanger. The bulk gas is 60.0 mol% water, 10.0 mol% ammonia, and 30.0 mol% air. The heat exchanger surface is at 42C, and for simplicity in evaluating properties, the entire operation is at 42C and 1.0 atm. The condensed and dissolved water and ammonia in the liquid are assumed to have a high mass transfer coefficient so that gas-phase mass transfer controls. The diffusion is across a stagnant gas film (Figure 15-1) with 8 = 0.01 m thick. Determine fluxes (N values) of the three components. N z=0 z=L G
