Question

in a rocket fuel is consumed at 100 kg/s. the velocity of gases ejected is 4.5×10^4. what will be the thurst acting on rocket.
​

Answer 1

Answer:

Explanation:Or: Force = change in momentum over change in time

P =mv

dP/dt = mdv/dt + vdm/dt

mdv/dt isn’t going to help much here, so let’s say it’s zero. This gives us velocity times mass flow.

Just multiply mass flow and exhaust velocity. 40 kg/s times 50000 m/s
