Insulation calculation to prevent condensation
Insulation calculation to prevent condensation
(OP)
Hello people
I need to calculate the thickness of insulation required for a cylinder of inner radius 20cm. The temperature inside the cylinder is -165°C and
outside temperature being 25°C.
similarly how does it vary for a wall of thickness 50cm.
Do i need to provide any more information or is this sufficient.
the insulation coating is intended to prevent condensation.
can somebody provide the formulae for the calculation.
thanks in advance .............

RE: Insulation calculation to prevent condensation
The air temp minus the dew point minus some margin is what the allowable convective temperature drop is. Use the convection equation to determine how much heat is allowed to flow inward. The allowable heat flow divided by surface temp minus the interior temp divided by thermal conductivity will get you to the required thickness.
