# Srm Loaded Hollow Cylindrical Grain Outside Radius 30 Cm Inside Diameter 15 Cm 60 Cm Lengt Q17797654

An SRM is loaded with hollow cylindrical grain of outside radius 30 cm and inside diameter 15 cm and 60 cm length. The propellant density is 1600 kg/m^3 and specific impulse of 200 s. The flame starts from left and propagates co axially at a speed of 2.5 cm/s. Calculate the total burning time and thrust produced after each 5 seconds. Plot the thrust time curve for this rocket. Calculate the maximum change in velocity at the rocket nozzle exit due to complete combustion of propellant if the rocket initial mass is 200 kg.
