Acommon procedure for measuring the velocity of an airstream involves the insertion of an electrically heated wire (called a krwzluh dqhprphwhu) into the airflow, with the axis of the wire oriented perpendicular to the flow direction. the electrical energy dissipated in the wire is assumed to be transferred to the air by forced convection. hence, for a prescribed electrical power, the temperature of the wire depends on the convection coefficient, which, in turn, depends on the velocity of the air. consider a wire of length / 20 mm and diameter ' 0.5 mm, for which a calibration of the form 9 6.25 105 k2 has been determined. the velocity 9 and the convection coefficient k have units of m/s and w/m2 k, respectively. in an application involving air at a temperature of 7 25c, the surface temperature of the anemometer is maintained at 7v 75c with a voltage drop of 5 v and an electric current of 0.1 a. what is the velocity of the air?
