de = dean_number(re,d,r,p=undefined)
Computes the Dean number given the Reynolds number , the helix radius and the pipe internal diameter . The Dean number is then defined as:
Optionally the pitch of the helix can be specified, in which case the following more complete definition of the Dean number will be used:
Reynolds number .
Pipe internal diameter ().
Helix radius ().
Helix pitch .
Returns Dean number , dimensionless.
Unknown amount of arguments supplied.
The given helical radius or any of the vector elements, if it is a vector are below or equal to zero.
The given pipe diameter or any of the vector elements, if it is a vector are below or equal to zero.
