A certain rocket has an effective exhaust velocity of 7000 ft/sec; it consumes 280 lbm/sec of propellant mass, each of which liberates 2400 Btu/lbm. The unit operates for 65 sec. The rated flight velocity equals 5000 ft/sec.
Calculate
a) the specific impulse
b) the total impulse
c) the mass of propellants required
d) the volume that the propellants occupy if their average specific gravity is 0.925.
