    A thin disk is maintained at 75 degrees celsius and placed on the surface of a large medium maintained at 10 deg C. The thermal conductivity of the medium is 1.4 W/m-deg C, and there is a heat loss of 36 W. The shape factor, S is closest to:

    a) 20 cm

    b) 40 cm

    c) 60 cm

    d) 80 cm.
