Question

Which is the relation between the specific $T _ { c }$attained in a rocket blast

• A. $I _ { s } \geq T _ { c }$
• B. and $T _ { c } ^ { 2 }$
• C. $I _ { s } \geq T _ { c } ^ { 1 / 2 }$
• D. $I _ { s } \geq 1 / T _ { c }$

Answer 1

Answer: (C)

$I _ { s } \geq T _ { c } ^ { 1 / 2 }$

Answer 2

When specific impulse is greater than critical temperature, then rocket blast takes place. So the condition $I _ { s } \geq T _ { c } ^ { 1 / 2 }$ is right.
