  1. The thrust F developed by a rocket motor is given by F = mv +A(P1-P2), 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,P1 and P2 are the pressures. Show that the equation given is dimensionally correct.

Dear Karan
 
F = [M L T-2]
 
mv = [M T-1] [L T-1] = [M L T-2]
 
A(P1 – P2) = AP = [L2] [M L-1 T-2] = [M L T-2]
 
Hence verified
