It is a rectangular concrete tank

Thanks. I assume this was derived from using the Bernoulli equation and an unsteady state material balance? I didn't get the same term on the right hand side...do you have the derivation as well?

I understand that the head pressure is going to decrease as the water level goes down which will affect the velocity of water leaving the tank...I am trying to develop an equation to get the time required to drain the tank.

I am a little rusty on my differential equations as I haven't seen them in a few years! I am looking for some direction on a question on a first order ODE. I am trying to find the time required to drain a tank that is open to atmosphere. Any help would be appreciated. Thanks!
