Insulation mean temperature calculator

Select conductivity at the mean temperature across the insulation.

Units

t_{m} = \frac{t_{h} + t_{s}}{2}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

t_{m} = \frac{420 + 110}{2} = 265
