HEAT AND MASS TRANSFER QUIZ

Directly proportional to the surface area of the body

Directly proportional to the temperature difference on the two faces of the body

Dependent upon the material of the body

All of these

Directly proportional to the difference of temperatures between the two bodies

Directly proportional to the surface area

Either (A) or (B)

Both (A) and (B)

Pb = pa/pv

Pb = pa × pv

Pb = pa - pv

Pb = pa + pv
