What is the definition of pressure shaft in dam construction in civil engineering?

Pressure Shaft is enclosed pipe/channel used to deliver/feed water to hydraulic turbines in respect of hydro power plant.


What is increased in a dam by raising the water level?

Water pressure on the dam.


Does the Hoover dam have a water generator?

Yes, the Hoover Dam has 17 water generators. The Hoover Dam generators produce in excess of 2,000 megawatts. Each generator has a shaft, excitor, rotor, and stator.


Why the base of the dam is made wider?

The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.


What is difference between penstock and pressure shaft?

A penstock is a pipe that carries water from the reservoir to the turbine in a hydroelectric power plant, while a pressure shaft is a vertical pipe that carries water under pressure from the penstock to the turbines. The penstock is typically horizontal and submerged in water, while the pressure shaft is vertical and carries water at high pressure.


How you can apply more load on shaft?

by applying more pressure on centre of midden of shaft


Is pressure lower at the bottom of a dam?

Yes, pressure is higher at the bottom of a dam because the weight of the water above it creates a greater force pushing down. This higher pressure at the bottom helps to support the structure of the dam.


What is a surge shaft in dam?

The purpose of the surge shaft to damp surges in the headrace tunnel of the underground hydropower plant. It dampens hammering in HRT and prevent it from bursting. It actually consist of an orifice, which helps in regulating the flow in HRT gradually. A surge shaft is one of the components of water conductor system of a hydr Power Plant. It is not a part in Dam but Dam can be one of the components of an hydro power Plant. If you have a very high head hydro power plant with a water conductor system or so called HRT, Pressure Shaft and a Steel Penstock then a Surge Shaft is necessary to dampen the Water Hammer pressures immediately occurring due to the Load rejection cases which are frequent and are related to fluctuations in the load demand and other deficiencies or machine faults or line faults etc. Due to water hammer pressure the flowing water into the turbines gets rejected and the water starts travelling in the form of back pressure or oscillating waves with a very high velocity or celerity. This has to be dampened or else there is a possibility of cracking of penstocks or collapse of tunnel linings etc.


What is pressure shaft?

Abnormal load on an earth dam is?

The abnormal load on the earth dam is the water pressure on the upstream side.Loads acting on dams are hydrostatic pressure, self weight, seismic loads.

What would happen to the air pressure if you took a barometer from a mountain top down into a mine shaft?
