Description Usage Arguments Author(s) References Examples
Calculates the Reynolds number, a unitless measure.
1 | Reynolds(V, L, v)
|
V |
Air velocity in m/s |
L |
The characteristic dimension, usually the vertical dimension. For reference, a cylinder's characteristic L would be its height, assuming it is standing on its end This L should be the same L as is used for the convective coefficient calculation |
v |
The kinematic viscosity returned from function airviscosity (Ta). |

function (V, L, v)
{
v<-airviscosity(Ta)
Re<-V*L/v
}
# Typical values for Reynolds numbers range from 6.6 to 6.6e+5
# Example calculation:
V<-1
L<-1
Ta<-20
v<-airviscosity(Ta)
