The thrust F developed by a rocket motor is given by F = mv +A(P 1 -P 2 ), where m is the mass of fuel ejected per unit time ,V is the velocity of the ejected gas ,A is the area of the nozzle,P 1 and P 2 are the pressures. Show that the equation given is dimensionally correct.

Question

Arun · Answer

Dear Karan F = [M L T -2 ] mv = [M T -1 ] [L T -1 ] = [M L T -2 ] A(P1 – P2) = AP = [L 2 ] [M L -1 T -2 ] = [M L T -2 ] Hence verified
