Fluid Flow: A pressurized cylindrical tank, 5.0 m in diameter, contains water that emerges from the pipe at point C with a speed of 84 m/s, as shown in the figure. Point A is 10 m above point B and point C is 3.0 m above point B. The area of the pipe at point B is 0.080 m2 and the pipe narrows to an area of 0.070 m2 at point C. Assume that the water is an ideal fluid in laminar flow. The density of water is 1000 kg/m3. The rate at which the water level is falling in the tank is closest to
A. 300 mm/s. B. 340 mm/s. C. 250 mm/s. D. 210 mm/s. E. 160 mm/s.
