(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Examine the schematic of the tower. Water flows in at the top to balance the water flowing out through the holes, so the height of the water in the tower stays fixed.

Take state 1 at the top of the water in the tower and state 2 in the water just as it flows out of the hole.

for this part there is a picture that shows a water tower there are three holes one on the top one in the middle and one at the bottom.

a. What is the pressure at states 1 and 2?Explain.

c. If the holes are at heights of 3.0 cm, 13cm and 23 cm above the surface of the water in the lower basin and the top hole is 3.0 cm below the top of the water in the tower, predict which one you believe will go farthest (top, middle or bottom). Explain your reasoning.

2. Relevant equations

P_{1}+1/2(m/V)v_{1}^{2}+(m/V)gy_{1}=P_{2}+(m/V)v_{2}^{2}+(m/V)gy_{2}

density = m/V

3. The attempt at a solution

a) I would say that the pressure is the same as the atmospheric pressure because that is the only pressure that i found it could affect in this problem in this case then pressure at both states are the same

b) If P_{1}and P_{2}then somehow i can manipulate the bernoulli equation to get a velocity but i dont know how

please help me
