The pump-turbine units were uprated in July 1972 from their initial rating of 175 MW each to 204 MW each, increasing the plant's overall rating from 350 MW to 408 MW. [3] [16] From 1998–1999, the turbine runners for both units were upgraded, resulting in improved flow rates and another power uprate to 225 MW per unit (450 MW total). [17] [16]
Aquifer test (or a pumping test) is a field experiment in which a well is pumped at a controlled rate and the aquifer's response (drawdown) is measured in one or more observation wells. [5] Cone of depression is a conically-shaped depression that is produced in a water table as a result of pumping water from a well at a given rate. [4]
In hydrology, a well test is conducted to evaluate the amount of water that can be pumped from a particular water well.More specifically, a well test will allow prediction of the maximum rate at which water can be pumped from a well, and the distance that the water level in the well will fall for a given pumping rate and duration of pumping.
Well intervention vessel Skandi Constructor. A well intervention, or well work, is any operation carried out on an oil or gas well during, or at the end of, its productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well.
A cone of depression is a circular area surrounding a well where groundwater levels are reduced from pumping. [1] [2] In an unconfined aquifer (water table), this is an actual depression of the water levels. In confined aquifers , the cone of depression is a reduction in the pressure head surrounding the pumped well.
Smithville Lake is a 7,190-acre (29 km 2) reservoir on the Little Platte branch of the Platte River in Clay County, Missouri near Smithville. It provides the water supply for Smithville, Missouri and Plattsburg, Missouri. Kansas City, Missouri has reserved a portion for its water supply.
Slow pump pressure is the circulating pressure (pressure used to pump fluid through the whole active fluid system, including the borehole and all the surface tanks that constitute the primary system during drilling) at a reduced rate. SPP is very important during a well kill operation in which circulation (a process in which drilling fluid is ...
This was enough to provide lighting, washing machines and some limited well-pumping or refrigeration. Wind-electric plants were used mostly on the Great Plains, which have usable winds on most days. In 1933, the Tennessee Valley Authority was created, in part, to provide rural electrification in the Tennessee Valley and surrounding areas.
