+//INPUT DATA
+L=0.609;//Height of the metal plate in m
+Ts=161;//Temperature of the wall in degree C
+Ta=93;//Temperature of air in degree C
+
+//CALCULATIONS
+Tf=(Ts+Ta)/2;//Film temperature in degree C
+k=0.0338;//Thermal conductivity in W/m.K
+v1=(26.4*10^-6);//Kinematic viscosity in m^2/s
+Pr=0.69;//Prantl number
+b=0.0025;//Coefficient of thermal expansion in 1/K
+a=(38.3*10^-6);//Thermal diffusivity in m^2/s
+Ra=((9.81*b*L^3*(Ts-Ta))/(v1*a));//Rayleigh number
+Nu=(0.68+((0.67*Ra^0.25)/(1+(0.492/Pr)^(9/16))^(4/9)));//Nussults number
+h=(Nu*k)/L;//Heat transfer coefficient in W/m^2.K
+Q=(h*L*(Ts-Ta));//Rate of heat transfer in W
