[net.physics] Hot-wire Anemometers

Can someone tell me the dependence of heat transfer by forced convection
past a body (circular cylinder perpendicular to the flow) upon velocity,
density of the air (air is the medium), temperature of the cylinder, and
temperature of the air, at low Reynolds numbers?  In other words, what
is the functional form of f, where

	dQ/dt = f (v, rho, Tw, Ta) ?

If one is clever, one or two of these devices can be used to read mass
flow rate of a gas directly.  This is my goal.
