Variables Used

Conduction Shape Factor - (Measured in Meter) - Conduction shape factor is defined as the value used to determine the heat transfer rate for the configurations which are very complex and require high calculation time.
Diameter of Sphere Insulated - (Measured in Meter) - The Diameter of Sphere Insulated is considered in the falling sphere resistance method.
Distance from Surface to Centre of Object - (Measured in Meter) - Distance from surface to centre of object is the distance between the surface and the center of the object.

STEP 1: Convert Input(s) to Base Unit

Diameter of Sphere Insulated: 4.466395 Meter --> 4.466395 Meter No Conversion Required
Distance from Surface to Centre of Object: 494.8008429 Meter --> 494.8008429 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = (2*pi*D_si)/(1+(0.25*D_si)/d_s) --> (2*pi*4.466395)/(1+(0.25*4.466395)/494.8008429)

Evaluating ... ...

S = 28.0000008743443

STEP 3: Convert Result to Output's Unit

28.0000008743443 Meter --> No Conversion Required

FINAL ANSWER

28.0000008743443 ≈ 28 Meter <-- Conduction Shape Factor
