Question
A wind tunnel nozzle consists of a smooth contraction from an inlet area A; = 0.6m? to an outlet A2 = 0.2 m?. The outlet velocity is Uz =40 m/s and the outlet pressure is p2 =P. =101.6 kNm?. Assuming incompressible flow of air with p = 1.225 kgm. Calculate (a) The inlet velocity U; (b) The inlet pressure p;. Also express p, as a pressure coefficient based on Uz2, ie evaluate C, = Pi - Pa (c) The external force required to hold the nozzle in position.
