Lubrication is the supply of oil between two surfaces that have relative movement. When applying lubrication to engine parts, one should choose a good lubricant to make the engine run efficiently. Applying Shell oil to engine part The objective of applying lubricatio…

A lubricant is a substance introduced to reduce frictional force and heat generation between surfaces when they move in mutual contact. A good lubricating oil generally possesses the following characteristics: Suitable Viscosity: Oil's viscosity should not change …

The comparison between static capacitors and synchronous condensers can be made based on factors like power factor, overloading, kVAR, system stability, power loss, installation, change of rating, and failure, listed below the table. S.no Static Capacitors S…

AC (Alternating Current) and DC (Direct Current) transmissions transmit electrical energy. Each has its advantages and disadvantages, making them suitable for different applications. Here is a comparison:. S.no AC Transmission DC Transmission 1 Require…

Energy cannot be created or destroyed but can only change from one form to another. The law of conservation of energy  does not distinguish between valid and wasted  energy . The law neglects ‘losses’ from the closed system into the environment. In an energy conservati…

Reinforced steel is commonly known as rebar (short for reinforcing bar) is an alloy of ferrous metal with 0.25 to 1.5 percent of carbon. The higher the carbon content, the harder is the steel. Steel bars of circular cross-sections are mainly used as reinforcement to s…
