Q4 see photo provided. Question 4At rated thrust, a liquid-fueled rocket motor consumes 80 kg/s of nitric acid as oxidizer and 32 kg/sof aniline as fuel. Upon combustion, flow leaves the nozzle axially at a speed of 180 m/s relativeto the nozzle. The pressure at the exit plane is 110 kPa. The nozzle exit diameter is D = 0.6m.Calculate the reaction force necessary to hold the motor on a test stand, placed horizontally onrails, at standard ambient pressure of 100 kPa.If this rocket is to be launched vertically, what is its maximum mass such that it can lift off theground?

Given: mass flow rate of oxidizer = 80 kg/s mass flow rate of fuel = 32 kg/s atmospheric pressure =…
