2. A two-dimensional square channel redirects a water flow from horizontal uniform to vertical nonuniform. The pipe width h=75.5 mm. The pressure is 185 kPa (abs) at the inlet and at atmospheric pressure at the exit with Vmax=2Vmin. The mass of the pipe is M=2.05 kg. The internal volume of the pipe is V=0.00355 m³. a. Find Vmin if U=7.5 m/s b. Calculate the force exerted by the pipe assembly on the supply Vmax 2 Vmin
