Expert Solution
Step 1
Given: Measured velocities and particle mass flow rates(velocity and Concentration) in complex duct at two section is given by figure 4.3 attached with the problem. The values shown are the ratio of observed value to the average value for the whole duct.
Average gas velocity = 39 ft/s
Average emission per unit area = 1.2 lb/ft2.hr
Find: Total volumetric flow rate of gas and total mass emission rate of the particles
