Gravitationally defined velocities for a low speed hot-wire calibrationA technique to provide the reference velocity for a low speed hot-wire calibration is described. A pivoted arm falls under the action of gravity and the resulting velocity field can be used to define the transfer function coefficients in a modified Collis and Williams (1959) relationship. In nominal agreement with a published result, a deviation from this relationship for a film Reynolds number such that Re exp n of less than about 0.24 is observed.
