Digital Twin Spark Ignition
This is used to get better combustion in combustion chamber.Double spark plug is used to obtain better combustion of fuel in cylinder head. It provide better efficiency and economical in fuel consumption

digital twin spark ignition engine which is used for better combustion.In which two spark plugs work at a time.one is used for starting the engine and the other used for initiating combustion.

Ref. working on the Vapor absorption System where the AC work on open air compression cycle.
Ref is closed cycle where AC is open cycle

refrigerator means fridge used as household appliance and can maintain temperature from 7 to -26 degree while air condition is used for human comfort and provides cooling effect in hot sunny days.

Glass lined reactor or GLR, it is a special type of reactor specially used in pharma and speciality chemical production plant where product material should be isolated from metal. its only a layer of coating in ordinary SS or ms reactor.

First we have to do priming and have to start the pump
priming is basically filling suction pipe with full of water.
off course we have to check is there any air leak in suction pipes

Procedure to operate a pump as fallows:- 1)Check the alignment of pump & motor coupling & all foundation bolts. 2)Fill the suction pipe with water & open vent of pump. 3)Close discharge valve of pump....

material for piping is SS.CS,PVC,HDPE etc. the selection is based on the specific application and corrosion of material.

Impeller - of a pump throws water form the impeller center to the periphery by the action of centrifugal force and go out through the small opening provided in the casing . in this process inside ...

A heat exchanger (HX) is a mechanical equipment used for exchanging heat, e.g. between two mediums i.e fluids.Its classified in two groups;1. Direct Contact HX2. Indirect Contact HXDirect Contact HX i...

heat exchanger is a device or arrangement used for heat dissipation of heat from a certain part where excess heat may be harmful to the system,heat exchanger increase the heat dissipation by simply in...

Mainly mech seals can be classified into single, double. m.o.c is carbon, silicon carbide, PTFE, etc.

Condenser improves P.Plant performance by reducing the pressure(due to change in phase i.e gas to liquid) at outlet of turbine.

Condenser changes vapour to liquid phase at constant pressure because pumping of vapour is not possible by pump.

is process by removing air that trap inside pump casing or at suction pipe, before filling a process liquid, open or remove the valve for air bleeding until you can't see any bubbles. 

Priming is the process of filling water in centrifugal pump suction strainer to casing upto the delivery valve or priming point. It will remove the air from the suction side of the pump. In centrifug...

Power for a centrifugal pump =  flow(M3/hr) x S.G x head(m) x density x g /(1000 x 3600 x 0.745 x pump efficiency )Head developed will depend only on the diameter of the impeller.  Head and flow is ...

boiler feed pump stages deliver high discharge pressure from pump to overcome the pressure inside the boiler drum and pressure losses from pipe connections, and also friction loss.

Boiler feed pump is a multi-stage centrifugal pump where no of impellers more than one usually >3 . Depending upon the boiler working pressure pump will select. The pump should have high positive suction to avoid cavitation, usually take more than 10m. feed water temperature will be more than>65'C.

It is condenser coil assembly. The Pressurized, hot refrigerant from screw compressor will pass through this coil, heat transferred between the tube coil and the surrounding, as a result the refrigera...

Tubes at the back of the refrigerator called as condenser.

Acc to A.P -- Weight of the water displaced is equal to the weight of the body. So the weighing scale indicate the same weight 105 kg.  but when we lift the body we will feel low weight due to the upward bouncy force. and body float/sink depend upon the bouncy force and metacentre. 

Firstly the question Cannot be directly related to Archimedes Principle, As the principle states that when an Body is immersed in water, The amount of water displaced by the body is equal to the weigh...
