Hey, thanks Ray - in this case, I'm assuming a bath tub has vertical edges, so the volume is directly proportional to the height helpfully. So in this time period \triangle t the net flow in is r \triangle t . Calculating the net outflow in this time period is what I'm finding hard as it is...

Homework Statement I've been asked to solve a problem where a bathtub is being filled at a constant rate, meanwhile water is draining out continuously. The bathtub fills with a constant flow rate of \frac{dI}{dt} and drains with a flow rate \frac{dO}{dt} which is directly proportional to √h...
