Chapter $7$ assignment: If you look at the picture below, you will see that water is draining out of the cylindrical tank from a hole in the bottom. Also, as you can see from the picture, there are $5$ important variables: D $($diameter of the tank$),$ h $($height of water in the tank$),$ g $($gravity$),D_o($diameter of the hole in the bottom$),$ and V $($velocity of water exiting the tank through the hole$).$ Since there are $5$ variables and only $2$ dimensions, there are $5-2=3$ PI terms. If each PI term has the repeating variables D and g$,$ find the three PI terms. You can submit a scanned pdf or an excel file.
