# Question: newtons law of cooling at corresponding to convective heat...

###### Question details

Newton's Law of Cooling at , corresponding to convective heat transfer with a fluid at temperature , was given in class by the boundary condition:

Suppose the temperature at is greater than the ambient temperature . Is the flux then positive or negative? What about the temperature gradient (positive or negative)? Do these signs make physical sense (explain)?
