Hi, and thanks for your expert opinions in advance. I'm working on a theorical scenario of a flue gas funnel. Assuming hot air is rising from a funnel at a constant rate. Would the hot air rise faster if water droplets were sprayed at the top of the funnel, hence lowering the air temperature at the top part of the funnel? Would this lead to an increased air pressure differential at the bottom of the funnel vs the top of the funnel, leading to hot air rising faster, and hence, creating a more powerful updraft?
