Incompressible steady flow in the inlet between parallel plates is uniform, Vo = 8 cm/s, while downstream, the flow develops into the parabolic profile = az(zo-z), where a is a constant. What is the maximum value of v? Vo

A water diffuser is constructed like that in the figure below. Diffuser wall 2 m Flow Entrance 7 m Exit The volumetric flow rate at the entrance (per meter depth into the plane of the image) is 14.0 m2/s and the pressure difference Pexit - Pentrance = 350 kPa. What is the expansion angle in degrees? i

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

A necked-down section in a pipe flow, called a venturi,develops a low throat pressure that can aspirate fluidupward from a reservoir, as in Fig. UsingBernoulli’s equation with no losses, derive an expressionfor the velocity V 1 that is just sufficient to bring the reservoirfl uid into the throat.
