A tiny temperature probe is fully immersed in a flowing fluid and is moving with zero relative velocity with respect to the fluid. The velocity field in the fluid is
v⃗=(2π₯)iΜ +(π¦+3π‘)jΜ , given and the temperature field is T=2π₯2 +π₯π¦+4π‘, where x and y are the spatial coordinates, and t is the time. The time rate of change of temperature recorded by the probe at (x=1, y=1, t=1) is?
Correct : d
