Design the amplifier circuit in fig. 1 such that ic = 1 ma and a, = 0.95 v/v. use supplies of vcc =
vee = 15 v, rsig = 50 1, and rp = 10 kl. find the value of ri that satisfies the design
requirements.
perform the following:

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
