Yep. This letter is another one of those letters I really have to stretch for in order to find a word even close to relevant to water, and therefore paddling. 108 more words

#### Theme: Aerodynamics - 2010 Kia Ray

**Not all aerodynamic cars have to draw on the same set of forms. The 2010 Kia Ray (or PHEW Ray) manages to look slippery without resembling a blend of Tatra and Citroen shapes.** 337 more words

#### The Reynolds number

The Reynolds number is largely defined as “the ratio of inertial forces to viscous forces” in a moving fluid. But, in plain english, this actually explains very little. 364 more words

#### Engineering Riddle - No. 5 (Fluid Mechanics) "Dimensionless"

#### Similarity requirements of a hydrodynamic model

**Why downscaling only works down to a certain limit**

When talking about oceanographic tank experiments that are designed to show features of the real ocean, many people hope for tiny model oceans in a tank, analogous to the landscapes in model train sets. 793 more words

#### Mixing Fluids in low Reynolds number

In the post on Laminar flow we see that it is hard to mix fluids when the Reynolds number of the flow is low. This is the kind of situation we are in when we want to mix small quantities of two fluids together say. 68 more words

#### Reynolds number

The Reynolds number is a property of a flow that (roughly speaking) measures the ratio of the rate of flow of a liquid to its viscosity. 217 more words
