 For q”s constant, the rate of heat transfer is expressed as
q =q”s As= m· Cp (Tm,o -Tm,i).
As: pi * D * L
Ts,x=Tm,x+ q”s /h

q =h
As= m· Cp(Tm,o -Tm,i)

The Vertical Plate: Lc=L
For laminar flow (104 <RaL < 109), C = 0.59 and n = 1/4,
For combined laminar and turbulent flow (109< RaL < 1013),
C = 0.10 and n = 1/3.
