+Too = 31.0+273.0                    //Ambient air temperature (K)
+D = 0.06                            //Diameter of sphere (m)
+g = 9.8                             //Gravitational acceleration (m/s^2)

+//Calculation:

+Ra = Gr*Pr                          //Rayleigh number
+
+//From equation 10.13:
+h = (k/D)*0.6*Ra**(1.0/4.0)         //Heat transferred from bulb (W/m^2.K)
+
+//Result:
