Hypothetical a–b alloy of composition 40 wt% b–60 wt% a at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively. if the composition of the α phase is 13 wt% b–87 wt% a, what is the composition of the β phase?

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

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
