A thermocouple bead is spherical in shape having a diameter of 2mm and is subjected to the same flow system as in Problem 12-11. Estimate the heat-transfer coefficient for such a configuration.
Problem 12-11
Using chart(s) in this chapter determine the heat lost by forced convection from a flat plat maintained at 350 K and subjected to atmospheric air at 300 K and a flow velocity of 50 m/s. The plate length in the direction of flow is 1 m.
