Explain the Working of Magneto Hydro Dynamic Generator with sketch.

Question 1 : Explain the Working of Magneto Hydro Dynamic Generator with sketch. Answer :  Magneto hydro dynamic generator also called MHD generator, the principle of MHD generator is based on Faraday's law of electromagnetic induction.  The MHD generator is a high efficiency heat engine that converts thermal energy into electrical energy.  According to Faraday's rules, when a conductor rotates in a magnetic field, a voltage is produced in it that produces an electric current.  MHD generator uses fluid as a solid conductor which is a conductor.  It can be a working liquid, ionized gas or a liquid metal.  When ionized gas flows through the magnetic field, a voltage is produced in it and this ionized gas behaves like an electric conductor.  The gas is used between 2000 ° -3000 ° K temperature.  This method of power generation does not contaminate the environment.  Installing an M.H.D power generator costs more than a conventional thermal...

Explain Depriciation.

The Depriciation refers to fall in the value or utility of fixed assets which are used in operations over the definite period of years. In other words, Depriciation  is the process of spreading the cost of fixed assets over the number of years during which benefit of the asset is received. By J.R Batlibai's definition : "Its a matter of common knowledge that all fixed assets such as plants , machinery, tolls , buildings , lease holds ,furniture etc. gradually "diminish in value " as they get older and become worth out by  constant use in the Business.

What is Maintenance? Type of maintenance ! Mechanical Engineering

Maintenance is the work that keeps mechanical assets running with minimal downtime. Machine maintenance can include regularly scheduled service, routine checks, and both scheduled and emergency repairs. It also includes replacement or realignment of parts that are worn, damaged, or misaligned. Types of Maintenance:  The main types of industrial maintenance are: corrective maintenance preventive maintenance predictive maintenance systematic preventive maintenance conditional preventive maintenance. Corrective maintenance As its name implies, corrective maintenance is carried out to correct deterioration and malfunctions of any equipment or production line as soon as they occur. If the failure that disrupts the production process has not been anticipated by other types of maintenance, such as preventive maintenance, industrial maintenance technicians deal with the problem as soon as it occurs. This is unplanned /unscheduled preventive maintenance or curative maintenance. This type of...
