This system, sometimes known as emergency feedwater, can be used to cool the reactor, if normal feedwater to the steam generators fails to work. It works by pumping water to the steam generators from reserve tanks or a larger body of water (e.g. lake, river, or ocean) to remove decay heat from the reactor by dumping non-radioactive steam to ...
Gravity does all the work. In all other instances, pumps are necessary. In day-to-day situations, available water is often contaminated, unhealthy, or even naturally poisonous, so that it is necessary to pump potable water from lower levels to higher levels, where it can be of use. A fresh water source in a lower stream, river, pond, or lake is ...
The pressure that is required to do so is equal and opposite to the water potential of the sample (Ψ leaf or Ψ total). [ 1 ] [ 2 ] Pressure bombs are field portable and mechanically simple, [ 3 ] which make them the predominant method for water potential measurements in the fields of plant physiology and ecophysiology .
The coolant (treated water), which is maintained at high pressure to prevent boiling, is pumped through the nuclear reactor core. Heat transfer takes place between the reactor core and the circulating water and the coolant is then pumped through the primary tube side of the steam generator by coolant pumps before returning to the reactor core.
The first law efficiency (from the First law of thermodynamics) is a measure of the conversion of the heat provided to the cycle into useful work. When accounting for real life losses and inefficiencies, real binary cycle geothermal plants have a first law efficiency of between 10-13%. [1]
In canal systems, pumping stations help replenish water lost through lock usage and leakage, ensuring navigability. Similarly, in land drainage, stations pump water to prevent flooding in areas below sea level, a concept pioneered during the Victorian era in places like The Fens in the UK. The introduction of "package pumping stations" has ...

The impeller pumps water from the first few feet of the water and expels it into the air. [4] This process utilizes air-water contact to transfer oxygen. As the water is propelled into the air, it breaks into small droplets. Collectively, these small droplets have a large surface area through which oxygen can be transferred. Upon return, these ...
