Repeat Problem 6.44 but assume that one wall is insulated while the temperature of the other walls increases linearly with x. From Problem 6.44: For fully developed laminar flow between two flat plates spaced 2a apart, find the Nusselt number based on the ??bulk mean?? temperature if the temperature of both walls varies linearly with the distance x, i.e. ??T/??x = C. The ??bulk mean?? temperature is defined as
