Lets say i have a continuous stream of exhaust gas flowing upwards into a tower with a known cross sectional area. Is the velocity of the gas simply veloumetric flow rate/cross sectional area?

 

Lets say the gas comes into contact with a spray of water droplets. How does the velocity of the exhaust gas change?

 

Thanks.

If you want to be methodical about it, then you have to consider the amount of water evaporated for your velocity calculation.

 

But I must say that its effect is negligible so I can just take the volumetric flowrate of your exhaust gas alone.
