Freon 12 at -400C is flowing thro a copper tube of 1 cm OD. The atm air is at 300C and film coefficient b/w the tube surface and air is 10 w/m2K. An engineer wanted to reduce the heat losses and added 6 mm thick asbestos (k = 0.1105 W/mK) insulation to the tube. Determine the % reduction in the heat loss due to this added insulation. Assume that the outer surface of the tube is at -400C Freon 12 at -400C is flowing thro a copper tube of 1 cm OD. The atm air is at 300C and film coefficient b/w the tube surface and air is 10 w/m2K.
