D 2 1.4. Bernoulli Equation: Water flows from a reservoir down a circular pipe of diameter D = 1.2 cm at the instant shown. The difference in height between the water's surface in the reservoir and the pipe's outlet is h = 2.8 m. Assuming viscosity is negligible, calculate the flow rate Q, in cm3/sec, at which water will exit the pipe at the instant shown. (Please state any assumptions you make). (3 points) Hints: Pressures at the surface of the reservoir and at the pipe's outlet are both equal to atmospheric pressure. To perform a calculation with the information provided, you will need to make an assumption.... Here's a hint about that assumption: the reservoir diameter is very large compared to that of the pipe, so the velocity of the fluid within the main reservoir (or the rate at which the free surface decreases in height) is much, much smaller than the fluid velocity exiting at the pipe's outlet
