A double-plane window consists of two glass sheets each of area `1 m^(2)` and thickness `.01 m` separated by a `0.05 m` thick stagnant air space. In the steady state, the room glass interface and the glass outdoor interface are at constant temperature of `27^(@)C` and `0^(@)C` respectively. The rate of heat flow through the window pane is (Given , ` K_("glass") = 0.8 W m^(-1) K^(-1)`, `K_("air") = 0.08 W m^(-1) K^(-1)`)
