The specific heat c of pure copper is given at 100, 200, 400, 600, and 800 k as 252, 356, 397, 417, and 433 j/kg k. employ lagrange interpolation to compute the values at 300 k and 500 k. also, compute numerical curve fitting and interpolation 301 the extrapolated value at 1000 k and compare it with the value of 451 given in the literature.

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
