A plane wall is placed to a room with a temperature of 39 ºC and the wall losesheat to the room by convection. An engineer covers the wall with 2.4 cm thickasbestos (k = 1.3 W/mK) material. The interface temperature of the wall andasbestos is measured to be 310 ºC. Determine the “h” (convection heat transfercoeff.) of the room if the maximum allowable outer surface (outer surface ofasbestos) temperature is 40 ºC.
