an inclined manometer is connected to a pitor tube to measure the velocity at the center of a circular duct. If the inclined manometer measured 2.3 inches of water and the minimum division on the manometer scale is 0.04 inches of water. What is the uncertainty of the velocty at the center of the pipe in m/s

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
