What is monochromatic checklite?
A device by which flatness or roughness of a glass surface is measured.
Creepage distance in insulators?
It is the shortest distance between the conductors measured along with the surface of insulators.
How iron area is decreased when flux density is more?
Your question is unclear, but flux density is a function of the cross-sectional area of the magnetic circuit in which the magnetic flux is established.Flux density (symbol: B) is defined as 'the flux per unit area'. If the flux is measured in webers (pronounced 'vay-bers') and the cross-sectional area is measured in square metres, then the flux density is measured in teslas(symbol: T) which is a special name given to a weber per square metre.
What is overall surface efficiency of fins?
it is ratio of the total heat transfer from the surface area associated with both the fins and exposed portion of the base to maximum heat transfer from same surface area (in ideal conditions we get maximum heat transfer)
How do you work a flow transmitter?
A device used to measure the flow of liquids in pipelines and convert the results into proportional electric signals that can be transmitted to distant receivers or controllers. a velocity over a known surface area is measured and then it can be converted to volumetric flowrate or mass flowrate if the density of the fluid is known.
