The draft tube is a conduit which connects the runner exit to the tail race where the water is being finally discharged from the turbine. The primary function of the draft tube is to reduce the velocity of the discharged water to minimize the loss of kinetic energy at the outlet.
Rear axle is the last member of power train. In most of automobiles, real axle is the driving axle. It lies between the driving wheels and the differential gear and transmit power from the differential to the driving wheels.
A stretcher is a brick laid such that the long, narrow side only appears on the face of the wall.
A frog is a depression in one bearing face of a molded or pressed brick.
Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines and also ACSR has less skin and proximity effects.
A fourstroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes -intake, compression, power, and exhaust- to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle, ie; one operating cycle requires two revolutions of the crankshaft.
In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier.
IGBT is a short form of Insulated Gate Bipolar Transistor, which is a combination of Bipolar Junction Transistor (BJT) and Metal oxide Field effect transistor (MOS-FET). It is a semiconductor device used for switching related applications.
The thermal efficiency increases with the increase in temperature and pressure of the steam entering the turbine. Thus high temperature and high pressure steam are used in thermal power plant.In thermal power plant, the pressure in the working fluid cycle is developed by the help to feed water pump.

Store can be underground/ on ground.
Sub floor is the foundation for floor.
