Recall that the tank filling problem in Stephanie Redfern Saylor

Question 16 / 40: Recall that the tank filling problem in Subunit 3.4 resulted in an ordinary differential equation dh/dt A = Q - fh, where h is the height of fluid in the tank, Q is the volumetric flow rate in, H is the height of the tank, A is the cross sectional area of the tank, and f is a parameter with units of length²/time. We may write this equation in a dimensionless form d η dτ = 1 - (fH/Q) η, where η= h/H. Which of the following definitions of τ is consistent with the dimensionless equation?

A tQ/AH

B fH/Q

C tf/AQ

D fAQ/t

Explanation:

One way forward is first to check whether each answer is dimensionless. Another way forward is to start with the differential equation and then divide each side by H/Q. Then group terms until you reach the form of the de/un/non-dimensionalized equation shown.
