Gatorade powder is produced from liquid Gatorade that is has been put through a spray dryer. At a manufacturing facility, a large cylindrical tank is used to spray liquid Gatorade through an atomizer forming droplets which allows the water evaporate and solid Gatorade to remain. The tank is 6.0 m tall and 3.0 m in radius. Liquid Gatorade is supplied to top of the tank and contains 70% by mass water. To evaporate the water and leave behind powdered (solid) Gatorade, dry air enters the bottom of the tank at a temperature of 167C. The air leaves the chamber at 311 m3min-1, 83C, and contains 12 mol% water. Assume that the chamber operates at 1 atm. a) At what rate (volumetric flow rate in m3 dry air min-1) does dry air enter the tank? b) Estimate the upward velocity (m/s) of dry air from the bottom of the tank (treat the tank as it if were a pipe). c) What is the production rate of powdered Gatorade from the spray dryer (in kg min-1)

To solve this problem we can use the principles of mass and energy balances a First lets find the rate at which dry air enters the tank We can use the given conditions at the exit and assume steadysta... View the full answer
