Acetone is being absorbed from air using pure water as the solvent in a concentrated absorber. The flow rate of the entering gas is 100 kmoles/hr and contains 0.1 mole fraction acetone. The outlet gas stream is to be lowered to 0.01 mole fraction acetone Required:
Sketch and label the process flowsheet

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
