A gas flows over a heated horizontal surface with a surface temperature that is uniform and higher in value than the temperature of the gas. The local convective coefficient in W/m².K of this flow with convective heat transfer can be given as a function of the distance x (in meters) from the beginning of the horizontal surface by: h = A xD + B x + C, where A = -2.4, B = 14.8, C = 9.3 and D = 2.7. Based on this information, calculate the average Nusselt number of the flow over the plate if it is three meters long. Consider: ρgas = 0.9950 kg/m³; kgas = 30 x 10-3 W/m.K. Note: Use the equations given in the book by Schmidt et al. for problem resolution.
