Water droplets at 87 0C in a cooling tower have an average diameter of 0.15 cm. the airstream, which moves at a velocity of 0.9 m/s relative to the water drop, is at 17 0C. Compare the heat transfer coefficient form water to air using just Reynolds number to determine hc and then with Nusselt number to determine hc. Nu for water drops is Nu= 2 + 0.6Re1/2Pr1/3.
