Given the flow parameter the following functions
can be determined:
 Pressure drop for a circular pipe or one of
equivalent hydraulic diameter given the
Reynolds number, diameter, velocity,
relative roughness and viscosity.
 Pressure drop for air in a circular pipe or
one of equivalent hydraulic diameter given
temperature, diameter, velocity and relative
roughness.
 Pressure drop for water, ethylene glycol
water or propylene glycol water in a circular
pipe or one of equivalent hydraulic diameter
given the temperature, mixture
concentration, diameter, velocity and relative
roughness.
