How can heat loss be reduced/ minimised
WebConduction. Conduction is where heat or cool air is lost from a building through a solid material such as a wall, windows, and roof. The heat is conducted through these … WebPb = η*Bmaxn*f *V. From the above equation, ‘Pb’ is the hysteresis loss. ‘η’ is the Steinmetz hysteresis coefficient which depends on the material. ‘Bmax’ is the density of highest flux. ‘n’ is the Steinmetz exponent, based on the material it ranges from 1.5- 2.5. ‘f’ is the frequency of the magnetic reversal for each second.
