Hysteresis loss is NOT a function of

Hysteresis Loss = Kh × BM1.67 × f × v watts

where

Kh = Hysteresis constant depends upon the material

Bm = Maximum flux density

f = frequency

v = Volume of the core

Hence the hysteresis loss does not depend upon the ambient temperature.

_______is a tube that brings water to turbines

Penstock

Penstock pipe is used to bring water from the dam to the hydraulic turbine.

Penstock pipes are made up of steel or reinforced concrete.

The turbine is installed at a lower level from the dam.

The penstock is provided with a gate valve at the inlet to completely close the water supply.

It has a control valve to control the water flow rate into the turbine.
