We have a heat transfer fluid flowing through a id copper tube at 0.85 m/s and 300 c. evaluate the heat transfer coeficient within the tube (hal. when it is being cooled to 250 c. the properties of the fluid at 275 c are r= 881 j/kg-c kg/m3, viscosity=0.15 cp-0.00015 pa-s, k=0.133 w/m-c, cp=2372j/kg-c
