[QUOTE="Swamp Thing, post: 6852526, member: 5126"] Sorry, I'm not sure which part of your response refers to which part of my question -- maybe I should have made the questions clearer. My bad. Here are the two cases : [ATTACH type="full" width="367px" alt="1675857595100.jpeg"]321948[/ATTACH] In the first case, define ##P_{NOZZLE}## as the pressure say 1 cm back from the tip of the spout. Will this be pretty close to atmospheric? Define ##P_{BACK}## as the pressure at the center of the blower spout for both cases. In the second case (with the horn attached), will ##P_{BACK}## be less than atmospheric by ##1/2 \rho v^2## ? In other words, will the blower see a lighter load with the horn attached? [/QUOTE]
