I'm building a scale model of my future tank. It's 1/3 so the 12' tank becomes 3', etc...

The intent is to look at flow along the long path (12' down, 8' side, 12' back = 32' travel)...

I'm using the concept of similitude from fluid dynamics so my scale model has an equivalent dynamic viscosity to my water tank:

But that means that I need to find a liquid that has 3 x the dynamic viscosity of water. Milk is close, but I'd need 150 gallons of milk... $$$

So - I'm thinking of mixing 50:1 splashless bleach to raise the viscosity of the scale model water instead...

thoughts?
