A nozzle is formed so that its cross sectional area converges linearly along its length. the inside diameters are 200mm and 100 mm at inlet and exit and the length of the nozzle is 1m. What is the convective acceleration at a section halfway along the length of the nozzle if the discharge is constant at 0.12 ?3/s.

For a flow in the xy plane, the x component of the velocity is u=3x2y-y3is given. Determine the y component for steady state and incompressible flow. Does this result also apply to unstable, incompressible flow? Why is that? How many possible y components are there? Discuss.

Consider an airplane flying with a velocity of 50m/s at a standard altitude of 11km. At a point on the wing, the airflow velocity is 60 m/s. Calculate the pressure at this point. Assume incompressible flow.

Using the figure depicted below, perform the following: (a) Calculate the minimum height h at which cavitation occurs. Indicate on the figure where the cavitation occurs. (b) Calculate the volume flowrate (in m³/s) if h = 25 cm. Be sure to state all assumptions. Note that section 2 opens to atmosphere. D1 = 5 cm h D2 = 10 cm Free Jet (1) 2 Water at 20°C
