Example 2 The power supplied to a heating pad which measures 1cm*1cm is 0.02w.The pad is mounted the surface of human surface (a flat plate)and is allowed to exchange heat by free convection to the surrounding air at 26C.The heat transfer coefficient for this configuration is 8 w/m2.C.Safety considerations require that the surface temperature not exceed 45C.Should the heating be operated under these conditions?Example 2 • The power supplied to a heating pad which measures 1cm*1cm is 0.02w.
