The burned gases of a rocket engine are ejected from the rocket nozzle at a speed of 17,000 ft/sec. If the weight of gas ejected is one pound per second, find the thrust developed by the rocket. I don't really have an equation to use here but my guess is F = M\32.2 * Ejection Velocity...

I think I might have it figured out now. 150 mph x 1.4667 = 220 ft/sec 50 F + 459.6 = 509.6 degrees Rankine. 14.1 x 144 = 2030 lbs/sq. ft. 13.9 X 144 = 2001.6 R = 1716 ρ = P/RT 2030 / (1716 * 509.6) = .002321 2001.6 / (1716 * 509.6) = .002289 P1 + ½ρV^2 = P2 + ½ρV^2 2030 +...

First, let me say I am not a engineering student but just a average person trying to get his pilots license and enjoy working with aerospace problems. My problem is: “An aircraft is flying at 150 mph. The atomspheric pressure is 14.1 lbs./sq in and the temperature is 50 degrees F. Find...

Thanks for the site for the book. So, does anyone have any recommendations on my question. I think we all agree on how to calculate the pressure but are my calculations correct for P2? And how do i calculate the velocity if the pressure was 13.9 lbs /sq in?

I would assume it would be P2 the stagnation pressure.
