Problem 4 A partly full water tank admits water at 85 N/s weight flow while ejecting water on the ather side at 5500 cm'/s. The air pocket in the tank has a vent at the top and is at 20°C and 1 atm. If the fluids are approximately incompressible, how much air in N/h is passing thraugh the vent? In which direction?

![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 m'/s.
