Question: b) A liquid with Prandit number 10 is heated while flowing through a tube in fully developed flow. Given that the Reynolds number is 1.2

b) A liquid with Prandit number 10 is heated while flowing through a tube in fully developed flow. Given that the Reynolds number is 1.2 x 105, calculate the Nusselt number c) Air is flowing in a long square duct with each side 50mm at a velocity of 0.5m/s. determine the Nusselt number given that k for air is 0.026W/mK, vis 15.7 x 10- 6m2/s while the Prandtl number is 0.72
