Problem 5.53 [Difficulty: 2] Given: Aircraft flying north with speed of 300 mph with respect to ground, 3000 ft/min vertical. Rate of temperature change is -3 deg F/1000 ft altitude. Ground temperature varied 1 deg F/mile. Find: Solution: We will apply the concept of substantial derivative t T z T w y T v x T u Dt DT Governing Equation: (Substantial Derivative) Assumptions: (1) Two-dimensional motion (velocity not a function of z) (2) Steady flow (velocity is not a function of t)
