Unformatted text preview: T=10x+4y. a) Determine, using the material derivative, the rate of change of temperature (with time) measured by a thermocouple moving with the fluid through the point x=3, y=2. b) Determine the rate of change of temperature (with time) measured by a thermocouple fixed at the point x=3, y=2 c) Sketch the streamline passing through the point x=3,y=2. If the thermocouple is at (3,2) at t=0, mark where it would be at t=0.01. How far has it moved in the x and y directions in that interval? What temperature does it read at the beginning and end of this interval? Compare the time rate of change of temperature calculated from DELTA(T)/DELTA(t) to what you got in a)....
