Considering a two-dimensional turbulent jet, give the expression of the discharge of entrained fluid in the jet flow. Compare the result with a two-dimensional laminar jet.
Comment
Let us remember that the discharge of entrained fluid in the jet flow per unit width equals:

Physically, the jet entrains some surrounding fluid as momentum is exchanged from the high-velocity region to the surrounding fluid at rest. The volume discharge Q increases with increasing longitudinal distance x.
