3. The figure at the right shows a tank that is open to the atmosphere at the top and has a pipe at the bottom, through which liquid exits.(a) Show that the expression for the speed of the liquid leaving the pipe is?1 = √2?ℎ(b) Calculate the speed v1 of the liquid leaving the pipe if the difference in height is h = y2 – y1 = 1.5 m.Hint: Assume that the liquid behaves as an ideal fluid (non-viscous). Therefore, we can apply Bernoulli’s equation, and in preparation of doing so, we locate two points in the liquid. Point 1 is just outside the efflux pipe, and point 2 is at the top surface of the liquid. The pressure at each of these points is equal to the atmospheric pressure (P1 = P2 = atmospheric pressure), a fact that will be used to simplify Bernoulli’s equation.Solution:(a) Show that the expression for the speed of the liquid leaving the pipe is?1 = √2?ℎFrom the Bernoulli’s equation?1 +12??12 + ???1 = ?2 +12??22 + ???2?1 − ?2 +12??12 + ???1 =12??22 + ???2Since the pressures at points 1 and 2 are the same, P1 = P2, then P1 – P2 = 0.0 +12??12 + ???1 =12??22 + ???212??12 + ???1 =12??22 + ???2 -------- continue until you arrive at ?1 = √2?ℎAdditional hint: h = y2 – y1 and if the tank is very large, the liquid level changes only slowly, and the speed at point 2 can be set equal to zero (v2 = 0). 3.
