Reply To: different fluids not acting differently

[Rob]

Same way as for an experiment. Pick a few positions and work it out. You're after a comparison, so as long as you're consistent you should be fine. Remember, the various dimensionless numbers and HTC are made up to help understand fluid flow, they don't control the flow. It's always taught backwards as cause & effect get muddled up: it's taken me years of looking at weird flowfields to really understand how things work!
