Extracted text: De ... dz Z. de Flow rate (qo) Hole diameter (h) Water inside the tank whose diameter (D;) has an initial height (Zo) as presented on the figure above. At time (0) equals to zero, a small plug with hole diameter (h) at the bottom was released and the water inside the tank starts to flow at a rate (q.). For a constant water density dz and no fluid flow losses. The differential equation ( -) that best describe flow of water inside de the tank during water drain is
