Bernoulli's Equation question

P + pgh + 1/2 pv^2 = P + pgh + 1/2 pv^2

I'm looking at this equation and I was wondering, if there was a hole in the bottom of a tank, would the top of the tank have higher velocity in flow than the bottom of the tank, or is it vice versa?

Atm pressure is the same so it cancels out. I make the left side the top and I make the right side the bottom and I set some heights with Top being less than Bottom height. It seems that the top of the tank would experience the fastest velocity. Is that right?😕

whenever dealing with the kind of problem you stated you always assume that the velocity at the top of the tank is 0. If you do that then the velocity at the bottom becomes Square root of 2gh (you can see this by playing around with the Bernoulli's equation),

Hope that helps!
