WebHe specified that the Merlin 1D has a weight of 1,030 lb (470 kg) pounds including thrust actuators, a current vacuum thrust of 162,500 pounds-force (723 kN), and an uprated … WebI know that the Merlin 1D is used in the Falcon first stage, ... and the nozzle has to be limited in diameter to the size of the rocket in any case, ... The ratio between the area of the nozzle throat and the end of the nozzle determines the pressure drop from the combustion chamber pressure to the exit pressure.
WebThroat pressure in M1D Vac is 5.59 [MPa] and the Mach number calculated equal to: 1.00083 [-] so it is maybe only the display mismatch (too thick line?) Pressures @ thorat for two engines are different but the assumption for the nozzle calculations was that the thorat Mach Number is equal to 1. http://www.b14643.de/Spacerockets_2/United_States_1/Falcon-9/Merlin/index.htm
