Amount of absorption in a tray tower. an existing tower contains the equivalent of 3.0 theoretical trays and is being used to absorb so2 from air by pure water at 293 k and 1.013 x 10 5 pa. the entering gas contains 20 mol % so, and the inlet air flow rate is 150 kg inert air/h m2. the entering water rate is 6000 kg/h - m 2. calculate the outlet composition of the gas. (hint: this is a trial-and-error solution. assume an composition of, say, y, = 0.01. plot the operating line and determine the number of theoretical trays needed. if this number is not 3.0 trays, assume another value of y 1, and so outlet gas on.)

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
