1. (15 marks): The open cylindrical tank in the figure contains water and is being filled as shown. Assume incompressible flow, with water = 1000 kg/m3. a) Write the mass transport equation and note that the flow may not be steady, which implies that the rate of change of mass in the control volume needs not be...

Problem 3 We wish to represent flow through the sketched constriction in an otherwise straight, parallel wall, two-dimensional channel of height Y. Flow through the channel is inviscid, incompressible and uniform far upstream with velocity V One way to study this problem is to introduce a concentrated vortex (vortex point) at a height Y above the lower wall. n) Write a formula for the streami function ψ of the flow: the formula must be written in Cartesian is constant at...

Water can be considered as a non-viscous incompressible fluid of density p. A laboratory set-up is such that water flows through a pipe, exhibiting a laminar and steady-state flow. At the top end of the pipe, the flow tube has a cross-sectional area A and point 1 (located on the central streamline) is exposed to the ambient environment. The pipe drops through a A vertical distance h7 while its area decreases to when it reaches point 2 (also on the...

A pump is pumping water at a flow rate of 1200 litres per minute. In the pump the mechanical energy of the water increases by 250 J/kg. The density of water is 1000 kg/m3. a) Determine the pressure difference between the pump outlet and the pump inlet. Assumptions: there are no frictional losses in the pump, and differences in velocity and elevation between inlet and outlet of the pump can be neglected. b) Show that the mechanical power added to...
