The simplest formulation to calculate the thrust of a rocket is given below. Here are some technical information for a specially designed rocket that will operate only with compressed nitrogen gas. The pressure of the trapped nitrogen gas is 10.0 bar and the pressure of the ambient conditions is 1.0 bar. Since the exit velocity of the gas is 2500m/s, the mass of the nitrogen gas coming out per second is calculated.

calculate.

F= mVe+ (Pe-Pa)Ae A pressurized nitrogen rocket with an exhaust outlet radius 4 cm and a weight 3 x 1000 kg must be suspended in air at least in a vertical position.

What must be the mass flow rate (m) of the gas coming out of the exhaust so that it remains
