Question

A vertical oil-filled electric heating panel, 1.6m long by lm high, has a
surface temperature of 84°C and convects freely from both sides. The
69
surrounding air is at 20°C. Using the correlation data given in the
lectures, calculate the rate of heat transfer by natural convection.
For air at 52°C , k =0.02816 W/mK, μ = 0.196 xl0-4kg/ms,
Cp = 1006J/kgK, ρ = 1.086 kg/m3
Answer: 1126 W steps how to reach this
