Estimate the heat loss from a vertical Inconel 625 plate of 16 mm thickness exposed to nitrogen at one atm and -20°C. The plate is 3.4 m high and 4.8 m wide. It is maintained at 80°C. Take the properties of nitrogen at mean film temperature, ρ = 1.1421 kg/m3 , k = 0.02620 W/mK, ν = 15.63x10-6 m2 /s and Pr = 0.713. Also calculate the percentage of heat loss increased/decreased, if the plate thickness is reduced to half thickness of the original.

Estimate the heat loss from a vertical Inconel 625 plate of 16 mm thickness exposed to nitrogen at one
atm and -20°C. The plate is 3.4 m high and 4.8 m wide. It is maintained at 80°C. Take the properties
of nitrogen at mean film temperature, ρ = 1.1421 kg/m3
, k = 0.02620 W/mK, ν = 15.63x10-6 m2
/s and
Pr = 0.713. Also calculate the percentage of heat loss increased/decreased, if the plate thickness is
reduced to half thickness of the original.
