Sorry guys I am just been a lazy git

A rad advertised with an output with a delta T of 50 , anyone know the calc that lets you convert it to a delta T of 40 .
Sorry I have it somewhere but rushing off out and been lazy .

Cheers in advance

If delta T 50 is 1, delta T 40 is 0.748

so multiply delta T50 by 0.748 to get delta T40

A rad with manufacturer rating of Delta t 50 and an actual rating of 42.5 is 81% of power. Is that what you mean? I have some calculations but not sure if they're what you're after.

Thats the one , cheers

Thats the one , cheers

calculation is: Correction Factor = ((Actual deltaT)/50)^1.3, or if the rads are rated differently, its the ((Actual deltaT/Specified DeltaT)^1.3
