    Find unit length heat lost and describe the thermal circuit.

    Copper pipe inside radius r1 = 1cm
    And thickness of pipe = 0.3 cm
    So pipe outside radius r2 =1.3cm
    Thickness of insulated material = 1cm
    Radius of pipe with insulation r3 =2.3cm
    Thermal conductivity of insulated material k2 = 0.024 W/mK
    Inside pipe temperature T1 = 1000C
    Surrounding temperature T2 = 200C
    Heat transfer coefficient h2 = 50W/m2K
    Radiation coefficient hr = 30W/m2K

    Problem 4.2:
    1.
    Copper pipe inside radius r1 = 1cm
    And thickness of pipe = 0.3 cm
    So pipe outside radius r2 =1.3cm
    Thickness of insulated material = 1cm
    Radius of pipe with insulation r3 =2.3cm
    Thermal conductivity of insulated material k2 = 0.024 W/mK
    Inside pipe temperature T1 = 1000C
    Surrounding temperature T2 = 200C
    Heat transfer coefficient h2 = 50W/m2K
    Radiation coefficient hr = 30W/m2K

    Fluxes will be equal for both cases either by ...
