Since we want a relationship between thrust, F (force) and heat added, Q (energy), well use the conservation of
momentum and energy equations. Thus using the conservation of energy, we ha

Problem 1
In this problem we need to nd po2 /po1 as a function of M1 . This can be done by using the jump equations relating
pre-shock pressure (p1 ) and post shock (p2 ) to the initial mach number (M1 ) and the denitions of the stagnation
pressures. Thus
