Calculate the heat transfer coefficient for a fluid through a tube having 6.0m length & 16mm inside diameter fluid flow rate is 0.33 kg/sec. Properties of fluid are as follows Density = 985 kg/m, Specific heat = 4190 J/kgk, Viscosity -0.5 x 10-Ns/m Thermal conductivity = 0.66 w/mk Also calculate the heat transfer coefficient if the flow rate is reduce to 0.01 kg/sec.
