A small metal bead (radius 0.5 mm), initially at 100°C, when placed in a stream of fluid at 20°C, attains a temperature of 28°C in 4.35 seconds. The density and specific heat of the metal are 8500 kg/m³ and 400 J/kg.K, respectively. If the bead is considered as a lumped system, the convective heat transfer coefficient (in W/m².K) between the metal bead and the fluid stream is
