Liquid water flows in an ASTM B75 copper tube at a mass flow rate of 3.6 g/s. The water enters the tube at 40C, and the tube surface is subjected to a constant heat flux at a rate of 1.8 kW. The tube is circular with an inner diameter of 25 mm and a length of 3 m. The maximum use temperature for ASTM B75 copper tube is 204C. Would the surface temperature of the tube exceed the maximum use temperature for the copper tube? If so, determine the axial location along the tube where the tube's surface temperature reaches 204C. Evaluate the fluid properties at 100 C. The fluid properties at 100C are cp=4217 J/kg.K, k= 0.679 W/m.K, = 0.282 x 10-3 kg/m-s, and Pr = 1.75. Is this an appropriate temperature at which to evaluate the fluid properties? 7C. ****** The surface temperature of the tube at the exit is The surface temperature of the tube is The axial location along the tube where its surface temperature reaches 204C is 100ct an appropriate temperature to evaluate the specific heat of water. 204C. m.
