His study of the distribution of cholera led to the source of the disease, a contaminated water pump ( the Broad Street Pump, whose handle he had disconnected, thus terminating the outbreak ) within the heart of the cholera outbreak.

Hydraulic power networks also developed, using pipes to carrying pressurized water and transmit mechanical power from the source to end users elsewhere locally ; the power source was normally a head of water, which could also be assisted by a pump.

Once the upper tray fills past the drain stop, it begins recirculating the water until the timer turns the pump off, and the water in the upper tray drains back into the reservoirs.

In a slightly more complex system, it is automated with a delivery pump, a timer and irrigation tubing to deliver nutrient solution with a delivery frequency that is governed by the key parameters of plant size, plant growing stage, climate, substrate, and substrate conductivity, pH, and water content.

Both the airstone and the water pump run 24 hours a day.

Here, on the hottest day, it is cool beneath the stone and fresh from the water flowing in the sluices at the bottom of the vaults.

In a stream that turns a mill-wheel there is a lot of water ; ;

the mill-pond is quiet, its surface dark and shadowed, and there does not seem to be much water in it.

It is covered ( partly ) with water, air is atop of that.

There is a mediocre restaurant at Sounion and I fed a thin little Grecian cat and gave it two saucers of water -- there was no milk -- which it lapped up as though it were nectar.

In view of the increasing shortage of usable surface and ground water in many parts of the Nation and the importance of finding new sources of supply to meet its present and future water needs, it is the policy of the Congress to provide for the development of practicable low-cost means for the large-scale production of water of a quality suitable for municipal, industrial, agricultural, and other beneficial consumptive uses from saline water, and for studies and research related thereto.

This shelter could be built in regions where water or rock is close to the surface, making it impractical to build an underground shelter.

These are particularly suitable for regions where water or rock is close to the surface.

It is estimated that about 542,250 miles of forest development roads, and 80,000 miles of trails, constitute the system that will eventually be needed to obtain the maximum practicable yield and use of the wood, water, forage, and wildlife and recreation resources of the National Forests on a continuing basis.

The sight of sleek inboards, outboards, and sailboats being wheeled smartly along highways many miles from any water is commonplace.

Ignorance of the law is no better excuse on the water than it is on land ; ;

Currently, marina is used to indicate a municipal or commercially operated facility where a pleasure boat may dock and find some or all of the following available: gasoline, fresh water, electricity, telephone service, ice, repair facilities, restaurants, sleeping accommodations, a general store, and a grocery store.

This is possible with water and other liquids that have a high surface tension.

There is still water in it.

The sink in the hinged panel above the bunk drains into the head and a five-gallon water tank is mounted on the bulkhead above the sink.

Of course, when your 6-inch torrent of water is released, it may cause a lot of comment as it passes through or by neighboring properties.

If your pool is located on or near sloping ground, it may have natural drainage which is certainly more desirable than to be faced with the annual expense and labor of first pumping out the water and then scooping out all the debris.

Consumed countrywide, this product features a peculiarity of its own in this area: it is not only prepared with hot water, but, driven by the region's high temperatures, it is common to see it prepared with cold water as well, in which case the beverage is known as tereré.

If sugars are heated so that all water of crystallisation is driven off, then caramelization starts, with the sugar undergoing thermal decomposition with the formation of carbon, and other breakdown products producing caramel.

Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind.

Other types of turbines can be driven by wind or falling water.

Electrical power is usually generated by electro-mechanical generators driven by steam produced from fossil fuel combustion, or the heat released from nuclear reactions ; or from other sources such as kinetic energy extracted from wind or flowing water.

It could be done by hauling buckets of water up the shaft or to a sough ( a tunnel driven into a hill to drain a mine ).

The waterline to width ratio is larger, allowing the thinner hulls to be driven through the water at higher speeds, as each works somewhat independently of the other ( s ).

This was driven in some part by scientific naiveté, namely an early belief that seawater was incapable of freezing ( as late as the mid-18th century, Captain James Cook had reported, for example, that Antarctic icebergs had yielded fresh water, seemingly confirming the hypothesis ), and that a route close to the North Pole must therefore exist.

The word (, plural, Arabic ) is driven from the root ( Arabic ) meaning smooth and easy flow water or direct flow path.

When driven up against the enemy and detonated, a hole would be caused below the water line.

The development and growth of complex, orderly crystals, as driven by the random motion of water molecules within a conducive natural environment, is another example of an emergent process, where randomness can give rise to complex and deeply attractive, orderly structures.

This plot driven format was driven often by a prop device, such as letter, or glass of water, that revealed some secret information.

The part directly in contact with the earth-the " earth electrode "-can be as simple as a metal rod or stake driven into the earth, or a connection to buried metal water piping ( though this carries the risk of the water pipe being later replaced with plastic ).

The cooling is wind driven: wind moving over the water cools it and also causes evaporation, leaving a saltier brine.

This mechanical device was, in some areas, driven by water power.

The smuggling was not restricted to water routes, as herds were readily driven across the uncontrollable land border.

When heated they liquefy ; and if the heating is continued, the water of crystallization is driven off, the salt froths and swells, and at last an amorphous powder remains.

While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron ore. Before smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.

While movement of water and minerals through the xylem is driven by negative pressures ( tension ) most of the time, movement through the phloem is driven by positive hydrostatic pressures.
