Question:

Let us attack Prob. 6.25 in symbolic fashion, using Fig. P6.27. All parameters are constant except the upper tank depth Z (t). Find an expression for the flow rate Q (t) as a function of Z (t). Set up a differential equation, and solve for the time t0 to drain the upper tank completely. Assume quasisteady laminar flow.
