Problem 1 A jet of water discharges into an open tank, and water leaves the tank through an orifice in the bottom at a rate of 0.003 m'/s. If the cross-sectional area of the jet is 0.0025 m² where the velocity of water is 7 m/s, at what rate is water accumulating in (or evacuating from) the tank? Problem 2 A river discharges into a reservoir at a rate of 400,000 ft'/s (cfs), and the outflow rate from the reservoir through the flow passages in the dam is 250,000 cfs. If the reservoir surface area is 40 mi², what is the rate of rise of water in the reservoir? Problem 3 The open tank in the figure contains water and is being filled through section 1. Assume incompressible flow. If the water level h is constant, determine the exit velocity V2 far the given data Vi = 3 m/s and Q, = 0.01 m³/s. O-0.01 m D,-S em D-7 em Water Problem 4 A partly full water tank admits water at 85 N/s weight flow while ejecting water on the other side at 5500 cm'/s. The air pocket in the tank has a vent at the top and is at 20°C a nd 1 atm. If the fluids are approximately incompressible, how much air in N/h is passing through the vent? In which direction? Problem 5 Oil (SG=0.91) enters the thrust bearing at 250 N/hr and exits radially through the narrow clearance between thrust plates.
