Your duty is to construct the above circuit and change Potentiometer resistance until you see 1v 2v……12v at the output voltage which is showing above and at each output voltage measure the resistance and current. Fill the table above and write at least 10-page report. Your input voltage is 12 volts which is constant. Do not change input voltage.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
