flow bench program

[horsepowerfreek]

I am thinking about designing a flow bench software program. A few of the formulas i was thinking about putting in the program are as follows
1)reynolds number formula
2)expansibility factor formula
3)dynamic viscocity formula
4)dynamic viscocity formula
5)kinematic viscosity formula
6)square root of pressure drop formula.
Does any one have any thought on this?
Thank you in advance
