Fluid fluid with a temperature of -20C passes through a copper cylindrical wire. The outer diameter of the wire is 10 mm. The wire is in contact with air at a temperature of 25C, which is h = 50 W / m2K. The heat conduction coefficient of the wire is k = 0.5 W / mK. It will be applied in different thicknesses. a) Calculation separately for the resulting heat transfer per m when 0, 2.5, 5 and 7.5 m are applied. b) To interpret which thickness will increase the heat transfer by calculating the critical diameter. c) Graph the insulation and heat transfer
