1000 kmol/h of rich gas with 25% c1, 15% c2, 25% c3, 20% nc4, 15% nc5 by moles is to be absorbed by 500 kmol/h of nc10 in an absorber operated at 80℉ and 4 atm. calculate, by kremser method, percentage of absorption of each component for 4, 10, 30 theoretical stages. what conclusion can you make from the calculations? use the depriester chart to find k-values.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
