What is the formula for temperature rise with tubes?
(a) temperature rise with tubes = total loss / dissipating surface*(12.5 + 8.8x)
(b) temperature rise with tubes = total loss * dissipating surface*(12.5 + 8.8x)
(c) temperature rise with tubes = total loss / dissipating surface / (12.5 + 8.8x)
(d) temperature rise with tubes = total loss + dissipating surface*(12.5 + 8.8x)
This question was addressed to me in a job interview.
I would like to ask this question from Design of Tank in section Design of Transformers of Design of Electrical Machines
