WebConsequently, you would want a small exit diameter. However, in my experiments I measured the thrust of a 12x12 inch propeller at around 5500 rpm and got 20 N without a nozzle (just a constant diameter duct) and only 4 N with a nozzle reducing the exit diameter to 50 percent of the prop diameter. These results are contrary to my theory! WebSep 27, 2024 · But that nozzle size (7/32") is very close to the rule of thumb of "1/3 ID for the nozzle" on core-burners. 1/3 of 3/4" would be about 0.2498" and 7/32 is 0.2188". The …
