TP Means Tie-in Point

Loads are not really transmitted to ground. Yes, there is parasitic induction due to capacitive coupling, but the return path for the hot conductor(s) is(are) another hot conductor(s) or neutral. While neutral is grounded, it is essentially a single point connection and, by Kirchoff's current law, has little or no current through ground.

It would seem that this is contradicted by the wye connection because, ultimately, neutral is grounded, making the ultimate return path to be ground. In fact, however, looking at the big picture, each leg in the wye connection is balanced, so it looks like a delta connection. Unless there is some fault, the net current on ground, as seen by the substation transformer, and by the earth ground between it and the service drop, is nominally zero.

40 stands for carbon percentage and 8 indicates the designation of carbon

Mass is the measurement of inertia, or resistance to change in motion. It is not to be confused with weight, a measurement of the force due to gravity exerted on an object.

For many practical purposes, mass and weight vary numerically by a constant, namely gravitational acceleration. Due to the common misconception of mass and weight being the same thing, units can often get confusing. For example, the English unit for mass is the slug, rather than the pound (a unit of weight). Some unit systems, such as the American Engineering System, take up the convention of making mass and weight numerically equal. In such a case, the units specify whether mass or weight is intended, so you would have pound mass (lbm) and pound weight (lbw). The SI unit for mass is the kilogram (kg), which, like the pound, is commonly and erroneously used as a unit of both mass and weight.

Jar is used in oil&gas industry specially in exploration of hydrocarbons.It is used to free the stuck string thus liquidating down hole problems.Jarring implies delivery of a heavy impact load to release the drilling string.A Drilling Jar is lowered along with Drill-string & it remains downhole as long as the Bit-Life.Fishing Jar is used during Fishing operations.D-Jars are more robustly built to with stand the bottom hole pressures&temperatures.

Most air compressors do not have a continuous load, as a result there is a need to control the amount of air entering the system.

One way to allow for load swings is to let the air surge tank pressure float between two pressures. To do this you can either start and stop the compressor automatically to stay with in the required pressure range.

Say pressure Pmin and Pmax. During normal requirement(load) of air, compressor will work at below Pmax.But when the requirement(load) decreases, delivery pressure start to increase. And when pressure equalise to Pmax,compressor start to unload(means pressure of the compressor start to decrease). During unloading air inlet valve is closed and delivery pressure decreases till it become equal to Pmin. Working of compressor in this phase is known as unloading.

As soon as pressure become equal to Pmin compressor start to load again till it reaches Pmax. working of compressor in this phase is known as loading.

According to Billy Gibbons of the band ZZ Top, sucker guage steel is "the kind of pipe they use to build windmills", as referenced in http://www.lowpft.com/sound.html

There are many but the best suited are those on which you can perform CAD-CAM...

many software do provide that facility ......

CEP is a Multi stage vertical Centrifugal Pump having double suction impeller at 1st stage for higher efficiency and high flow rate .Pump operates at marginal difference between NASHa and NPSHr so pressure equalising line is provied at suction side .CEP suction is conected to Hotwell and above hotwell Vacuum is maintained as per turbine design.

The purpose of CEP is transfer water to deaerator through LP heaters.

Shaft couplings are used to couple or attach two shafts together, typically in an assembly where one shaft rotates and drives the other shaft -- for example, if a motor were to drive a pump, there would be a coupling between the two shafts.

Shaft couplings can be rigid (accommodating no misalignment) or flexible (accommodating some angular and/or radial misalignment of the two shafts). More information on various types of couplings is available here:

main two type of bearing used in steam turbine:(1)thrust bearing (2)general bearing

11 gauge steel is 0.125 inches thick.

The guaranteed heat rate, indicated on performance data table of power plant is calculated in accordance with

the following formula:

HR = (Qms x Hms - Qfw x Hfw + Qhrh x Hhrh - Qcrh x Hcrh - Qas x Has + Qmu x Hmu) x 3600 / W

HR = heat rate [kJ/kWh]

W = gross power output [kW]

Q = mass flow [kg/s]

H = enthalpy [kJ/kg]

Subscript:

ms = main steam

fw = boiler feedwater

hrh = hot reheat steam

crh = cold reheat steam

as = auxiliary steam extraction from turbine cycle for boiler users

mu = make up water at condenser
