A hot wire anemometer is a device that is used to measure the velocity of flowing fluids. Such a device is employed to measure the air speed in a wind tunnel. The air flow is directed perpendicular to the 5 micro meter diameter, 1.25 mm long wire. A current of 24 mA is supplied to the wire, and the electrical resistance of the wire is 6 ohms. The wire temperature is 345 K. The air temperature and pressure are 300k and 1 atm, respectively. Estimate the tunnel air speed.
