Hi am a bit stuck on understanding how these two correlations can be similar I am wondering if anyone can ahead any light
Can anyone solve
Correlation for heat transfer by natural convection from a horizontal pipe to atmosphere is;
Nu = 0.53Gr^0.25Pr^0.25
Nu = hd / k
Where, Gr = αρ²d³(Ts-Tf)g / μ²
And Pr = Cpμ / k
Show that the above correlation can be simplified to;
h ≈ 1.34 (Ts-Tf / d)^0.25
α=3.077 x 10^-3
ρ=1.086
Cp=1.0063
k=2.816 x 10^-5
μ=1.962 x 10^-5
