Q.3 A firm produces frozen fruits and vegetables, and a venturimeter is used in this process.In a certain step of the process, the cherries are introduced to the cold air stream at -12oC with a 3 in. pipe connected vertically to the throat of the venturimeter. Venturimeter is connected to a pipe 4 in. in diameter. If the air velocity in the throat is 5 times the terminal velocity of the cherries and the ratio of throat/pipe diameter is 0.6, what should be the flow rate of air? Assume that the density of cherries is 1200 kg/m3 and the average diameters are 12 mm. What should be the lay-out of the pipeline between venturimeter and freeze-dryer to prevent the striking of the cherries to the walls? Is there any settling possibility of the cherries at the exit of the venturimeter?
