MEASUREMENT OF POWER:

“Power is generally done by dynamometers”

Types of dynamometers:

Absorption dynamometers

Driving dynamometers

Transmission dynamometers

Mechanical Dynamometers:

“Mechanical energy is converted in to heat through dry friction between the

Wooden brake blocks and the flywheel of the machine.

D.C. Dynamometers:

“Is usable as an absorption as well as transmission dynamometers”

Eddy current:

Hydraulic dynamometer

Diaphragm

Typical diaphragm pressure gauge
