Question

you are asked to measure the rate at which waste gases are being discharged from a stack. the gases entering contain 2.1 mole% carbon dioxide. pure carbon dioxide is introduced into the bottom of the stack at a measured rate of 4.0 lbm/mine. you measure the discharge of gases leaving the stack. and find the concentration of carbon dioxide is 3.2 mole%. draw and label the flowchart of this process and do the degree-of-freedom analysis. calculate the rate of flow in lb-mol/min of the entering waste gases

Answer 1

Answer:

Explanation: You are asked to measure the rate at which waste gases are being discharged from a stack. The gases entering contain 2.1 % carbon dioxide. Pure carbon dioxide is introduced into the bottom  

of the stack at a measured rate of 4.0 lb per minute. You measure the discharge of gases leaving the stack, and find the concentration of carbon dioxide is 3.2 %. Calculate the rate of flow, in lb mol/minute, of the entering waste gases
