Explain about the double-crucible method.
Low loss fibers are mostly manufactured by using double crucible and vapour phase deposition method.
The double-crucible method is the mainly common direct melt procedure. The double-crucible process combines the molten rods in a single perform by using two concentric crucibles. Optical fibers are drawn by this molten glass by using a same fiber drawing process as into vapor phase oxidation. A demonstration of a fiber drawing apparatus by using the double crucible process is illustrated in the given figure.

Places where friction occurs Locate the places on several mechanical devices where parts rub together. Roller skates, pulleys and the wheels of toys often required oil. Try to
Define isothermal process For isothermal process temperature remains constant i.e. Δu = 0. Thus according to first law of thermodynamics ΔQ =Δw Heat supplied to the syste
Work: In its technical sense, work is the product of force and distance, and work is done only when a force causes movement. We can see this by the formula: Work = Force x
