Absorption of Ammonia in a Tray Tower. A tray tower is to be used to remove
99% of the ammonia from an entering air stream containing 6 mol % ammonia
at 293 K and 1.013 × 105 Pa. The entering pure water flow rate is 188 kg
H₂O/h·m² and the inert air flow is 128 kg air/h- m². Calculate the number of
theoretical trays needed. Use equilibrium data from Appendix A.3. For the
dilute end of the tower, plot an expanded diagram to step off the number of
trays more accurately.

RP-1 is highly refined form of kerosene used for many first stage rocket engines. The average composition of it is indicated by CH1.9 a. What is the stoichiometric mixture ratio (MR) for RP-1 and oxygen? b. Now, you have a mixture of air and RP-1 with three times more air (in terms of moles) than is needed to burn all the fuel. How high is the final temperature? The heats of formation are given in the table below. In molar quantities, assume 1 mole of air is (O2+3.76N2). The reactants have a temperature of 25°C before combustion. You may use the average values of the specific heats for each constituent. C.
