Consider refrigerant R-134a flowing in a smooth, horizontal , 10-mm-inner-diameter tube of wall thickness 2 mm. The refrigerant is at a saturation temperature of 15 C for which the vapor density is 23.75 Kg/m^3 at a flow rate of .01 Kg/s. Determine the maximum wall temperature associated with a heat flux of 10^5 w/m^2 at the inner wall of the tube at a location .4 m downstream from the onset of boiling for a tube fabricated of pure Copper.
