A large storage tank, open to the atmosphere at the top and filled with water, develops a small hole in its side at a point 10 m below the water level. Assume the tank is large so the velocity of the water at the top of the tank is zero. The rate of flow from the leak is 2.5×10-3 m3 /min. Determine the speed at which the water leaves the hole. Determine the diameter of the hole.

rn=0.17 cm (nozzle radius)rh=0.95 cm (garden hose radius)Q=0.65 L/s (flow rate through the hose) Calculate the maximum height to which water could be squirted with the hose if it emerges from the nozzle in meters.

24) As shown in the figure, a large open tank contains a layer of oil (density 450 kg/m) 24) floating on top of a layer of water (density 1000 kg/m3) that is 3.0 m thick, as shown in the sketch. What must be the thickness of the oil layer if the gauge pressure at the bottom of the tank is to be 8.5 x 104 Pa? oil 3.0 m water Sketch: Fguations: Dah

1. The 3 cm diameter water pipe in the figure splits into two 1 cm diameter pipes. All pipes are circular and at the same elevation. At point A, the water speed is 2 m/s and the gauge pressure is 50 kPa. Assume Pwater = 103 kg/m³. The viscocity of water n = 0.001 Pa.s Cross-section view of pipe AO B a) What is the water speed at point B? m/s b) Calculate the Reynolds number, Re, for the fluid flow in region A and region B. Re in pipe A = Re in pipe B = c) The flow is at point A and at point B.
