Time required to raise Temperature knowing heat transfer rate
Knowing the heat transfer rate q, how long does it take to lower a fluid from temperature T0 to Tf?
This is for convective heat transfer from a heated body submerged in a fluid.
I'm looking for an appropriate formula (google isn't helping)

Other issues arise with the rate that heat can move from the insides of the body to the surface where it can depart to the surrounding medium. This is a much more complex problem. However, if the thermal conductivity of the submerged object is much greater than the conductivity between the body/fluid interface, then the effects may be negligible. Look up "heat conductivity" or "thermal conductivity".
Also look up "Newton's law of cooling".
