Want this question answered?
To deoxygenate the water, thus preventing corrosion
1- valve closed 2- pilot light not lit and thus no flame to heat the water (electric not working) 3- someone forgot to run a H/W line to a fixture
The water comes into the system via madreporite.
The irrigation system is the process of supplying water to a field etc... through a system of tunnels or canals that run through the field.
This is mainly to protect against any possibility of nuclear radioactive material pollution. For example in pressurized water reactor types, the three water systems are:Primary coolant closed system that extracts heat from the nuclear fuel that is undergoing nuclear fission,Secondary coolant closed system that gets heat from the primary coolant system and get converted into steam that goes to spin the turbines and get condensed again in the condenser and returns back again, andUltimate heat sink system that gets water from a river, sea, or ocean to cool and condense the steam passing through the condenser.
It does not. Look up the definition. Alot of time when we build a "closed system" is not really a closed system. Close, but not all of the way there. That is why you have make-up water on mechanical closed loops and why you add water to your radiator.
Closed System
The Roman baths were a cultural custom and their presence evolved over a period of time. It is not known when the baths were developed nor who "invented" them. When we read about the Roman baths, even the very early ones, they are already developed into the form (hot, warm, and cold rooms) with which we are familiar.
Sea stars use their water vascular system for circulation, excretion, and movement. This is a closed circulatory system because the fluids (water mostly) all travel through a series of stone, radial, and ring canals.
No, you still get fresh water and dispose of the dirty. A closed system filters and reuses the same water.
It is a closed system because water is not made or destroyed there on a large scale.
Closed. It also has a water-vascular system. :)
If its not closed properly water will leak out when the pump us running.
Since there are no net gains or losses, this cycle is known as a closed system. The rate at which water moves through the system will vary; some will be strrored for thousands of years in the deep oceans and ice caps. In contrast water remains only a short time in the atmosphere before returning to Earth as precipation.
it is a closed system, the earth operates on a water budget in which deficits in one part are balance by gains in another part.
In a closed system water vapors doesn't have an exit.
In a closed system, water can be boiled until it produces water vapor (steam). If the steam is then condensed through a coil of tubing and collected in another container, the same volume of water winds up in the second container that you started with originally. An action created and then reversed to it's original point. Note that this is in a closed system.
