Heating mantle, est. watts to temp?

Is there anyway to estimate the max temperature for a heating mantle given the diameter and the watts? Please forgive me if this is a stupid question.

The only stupid question is the one that is not asked.

Max temp for heating mantels seem to be 450o C, however,
ones designed for 650o and 750o can be had.

Wattage is a function of size. 60w for 50 ml upto 2 x 2 000w
for 72 000 ml [hemi] bottom / 1 000w for its top.
So sez the catalogue I eyeballed.

Haven't got a clue. :D
But here are figures for mantles with a 450°C maximum temperature. They require a controller to prevent overheating. So the figures should give you some indication..
Code:
diameter (mm) volume (liter) Power (Watt) 83 0.250 180 101 0.500 270 137 1 380 170 2 500 183 3 500 220 5 600 293 12 1300 347 22 1540

At the risk of pandering to the pedestrian - wattage count's
for nothing... la mantel has to fit whatever you want to heat
perfectly. They make them for funnels/RB flasks/reaction kettles/
&c of varying sizes up to 72 000 cc.
