OBTAIN INCIDENTAL HEAT TRANSFER
Heat input (Q) =
Determine kair at Heat conducted through the air lamina
Qair =
Incidental heat transfer
Qloss = Q - Qair

OBTAIN THERMAL CONDUCTIVITY OF OIL
Heat input (Q) =
Qloss from the calibration curve at given
Heat conducted through oil Qoil = Q - Qloss
Thermal conductivity of oil
