Water at a temperature of 293 K flows across a 5.0-cm outer-diameter tube that has a surface temperature of 393 K. By idealizing the vicinity of the stagnation point as a flat surface that is perpendicular to the flow direction, calculate the local heat transfer coefficient and heat flux at a point that is located at 0.5-cm distance from the stagnation point in the azimuthal direction.
