Specific impluse of a rocket and the critical temperature of the fuel reacted in the motor of the rocket has the relationship

A

`I_(s) prop sqrt((1//T_(c)))`

B

`I_(s) prop 1//T_(c)`

C

`I_(s) prop sqrt((T_(c)))`

D

`I_(s) prop T_(c)`

Text Solution

Verified by Experts

The correct Answer is:
C
The energy of propellant is measurement in terms of a specific impulse inside the motor of the rocket. It depend upon the flame temperature and average molecular mass of the gaseous products coming ot of the rocket nozzle. The specific impulse is given by the following relationship with the average molecular mass M and the flame temperature T, `I_(s) = sqrt(T_(c)//M)`.

A satellite of mass m is going around the earth in a circular orbital at a height (R)/(2) from the surface of the earth. The satellite has lived its life and a rocket, on board, is fired to ake it leave the gravity of the earth. The rocket remains active for a very small interval of time and imparts an impulse in the direction of motion of the satellite. Neglect any hange in mass due to firing of the rocket. Find the minimum impulse imparted by the rocket to the satellite. Find the minimum work done by the rocket engine. Mass of the earth = M, Radius of the earth = R
