Q.4 In an experimental setup, mineral oil is filled in between the narrow gap of two horizontal smooth
plates. The setup has arrangements to maintain the plates at desired uniform temperatures. At these
temperatures, ONLY the radiative heat flux is negligible. The thermal conductivity of the oil does not
vary perceptibly in this temperature range. Consider four experiments at steady state under different
experimental conditions, as shown in the figure Q1. The figure shows plate temperatures and the heat
fluxes in the vertical direction. What is the steady state heat flux (in W m) with the top plate at 90°C and
the bottom plate at 45°C?
