**1. A large tank isopen to the atmosphere and is filled with water. A small hole is 16m below the surface of the water. If the flow rate of the water is out of the hole is 2.5e^3 m^3/min, calculate: a)the velocity of the water as it leaves the hole and b) the diameter of the hole.**

**2. Lets say the pool is 1 and the hole is 2, P = pressure and**

*P*is density, i was given the equation: P1 +*P*v1^2 + 1/2*P*Y1 = P2 + 1/2*P*V2^2 + PY2**3. I have no clue how to solve this equation, can someone help me out please?**
