Using the vapor pressure-temperature relationships for caf2(α), caf2(β), and liquid caf2, calculate:

a: the temperatures and pressures of the triple points for the equilibria caf2(α) - caf2(β) - caf2(v) and caf2(β) - caf2(l) - caf2(v)

b: the normal boiling temperature of caf2

c: the molar latent heat of the transformation caf2(α)-> caf2(β)

d: the molar latent heat of melting of caf2(β)

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
