Molten metal at 2000 C is poured using crucible. The liquid metal jet has a diameter of 3 mm with an insulation shield of 5 cm diameter. There is a slit of 30 degrees around the insulation shield. The temperature inside the room is 30 C and the shield is 700 C. Assuming black bodies, find the net heat transfer between jet and shield, jet and room, shield and the room. One of the steps is wrong? Slit doesnot participate in radiation To find the view factor between metal and shield , ratio of the angles is used View factors are one of the most important steps to solve the problem None of the given Resistance network is required to be built
