WebSince in the case Sal showed us there is mass flow (or mass flux), the flow into the nozzle must be equal to the flow out of the nozzle (because the flow can't go anywhere but out the other end). The flow at the entrance and the flow at the exit is given by the same equation (density)* (area)* (velocity). ( 11 votes) Show more... Anirudh Deshpande
