How to measure turbidity?
The turbidity is measured by a turbidity rod or by a turbidity meter with optical observations and is expressed as the amount of suspended matter in mg/l or parts per million (ppm). For water, ppm and mg/l are approximately equal. The standard unit is that which is produced by one milligram of finely divided silica (fuller’s earth) in one litre of distilled water.
How does a turbidity meter work?
In general, a turbidity meter works on the principle of measuring the interference caused by the water sample to the passage of light rays. Jackson’s candle Turbidimeter: The height of water column will therefore be more for less turbid water and vice versa. Longer the light path lower the turbidity.
How to measure the extent of taste in water?
The extent of taste or odour present in a particular sample of water is measured by a term called odour intensity, which is related with the threshold odour or threshold odour number. Water to be tested is therefore gradually diluted with odour free water, and the mixture at which the detection of odour by human observation is just lost, is determined. The number of times the sample is diluted represents the threshold odour number. For public supplies, the water should generally free from odour, i.e. the threshold number should be 1 and should never exceed 3.
How to find suspended solids in water?
The suspended solid can be found by filtering the water sample. Total permissible amount of solids in water is generally limited to 500 ppm.

2. pH value of Water. If concentration increases, pH decreases and then it will be acidic. If concentration decreases, pH increases and then it will be alkaline. pH + pOH = 14 if the pH of water is more than 7, it will be alkaline and if it is less than 7, it will be acidic.
Why is water important to the Earth?
Believed to have initially arrived on the surface through the emissions of ancient volcanoes, water is a vital substance that sets the Earth apart from the rest of the planets in our solar system. In particular, water appears to be a necessary ingredient for the development and nourishment of life.
How much water is on Earth?
Viewed from space, one of the most striking features of our home planet is the water, in both liquid and frozen forms, that covers approximately 75% of the Earth’s surface. Geologic evidence suggests that large amounts of water have likely flowed on Earth for the past 3.8 billion years—most of its existence. Believed to have initially arrived on the surface through the emissions of ancient volcanoes, water is a vital substance that sets the Earth apart from the rest of the planets in our solar system. In particular, water appears to be a necessary ingredient for the development and nourishment of life.
What are the three processes that contribute to the hydrologic cycle?
Together, evaporation, transpiration, and sublimation, plus volcanic emissions, account for almost all the water vapor in the atmosphere that isn’t inserted through human activities. While evaporation from the oceans is the primary vehicle for driving the surface-to-atmosphere portion of the hydrologic cycle, transpiration is also significant. For example, a cornfield 1 acre in size can transpire as much as 4,000 gallons of water every day.
How does water vapor affect the Earth?
Water vapor is a powerful greenhouse gas, and it is a major driver of the Earth’s weather and climate as it travels around the globe, transporting latent heat with it.
What causes water to rise in the ocean?
A primary cause for increased mass of water entering the ocean is the calving or melting of land ice ( ice sheets and glaciers). Sea ice is already in the ocean, so increases or decreases in the annual amount of sea ice do not significantly affect sea level.
What is the mechanism that transports water from the atmosphere to the Earth's surface?
Cloud droplets can grow and produce precipitation (including rain, snow, sleet, freezing rain, and hail), which is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface. When precipitation falls over the land surface, it follows various routes in its subsequent paths.
What is the water cycle?
The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface. This gigantic system, powered by energy from the Sun, is a continuous exchange of moisture between the oceans, the atmosphere, and the land.

What is a water feature?
Water features can be a wonderful addition to your garden, as they create a soothing, calm atmosphere from the trickling of the water as well as adding an interesting focal point to your outdoor space.
Is it better to put a water feature in a garden?
It’s much easier to get a water feature to look good if it's placed in amongst plants and other existing garden greenery rather than at the centre of a space on its own. Nestled among the plants it doesn't matter if it's a bit too big or small and will blend in much better.
Does water smell in winter?
Water will get slimy eventually and start to smell a bit, especially during the winter, so make sure you ask the store how to drain it the feature, dismantle it and clear out the reservoir, if you are unsure. It is better to ask to find out for definite rather than cause any unnecessary damage to your feature.
Can you enjoy water feature at night?
Think about lighting the water in the feature, this creates a lovely effect, meaning you can enjoy the feature during the night too.

Why is the specific heat of water so high?
The specific heat of water is quite high. This enables water to absorb and release heat slowly, thereby regulating the temperature of its environment.
Why is water important to agriculture?
Water is necessary for the irrigation of crops and is, therefore, an integral part of agriculture. It is widely used in cooking activities since it boils at a temperature of 100 o.
Why is water important for photosynthesis?
Since water can rise in capillary tubes without any external help, it can be transported from the roots of trees to every other part of the tree. Water is an integral part of photosynthesis. Without it, autotrophic plants would not be able to produce their own food.
How does water help animals?
Water helps maintain body temperatures in plants and animals. In order to decrease the temperature in their bodies, animals lose water via perspiration (sweating) and plants lose water via transpiration.
Why is a water feature important?
A beautiful, well-constructed water feature increases the value of your property. It’s an investment in time (building and maintenance) and cost of materials.
Why does water go down?
Water goes down to ‘seek its own level’. Hygroscopic tension forces water sideways when moisture follows the underside of a spill rock or fallen branch. Soil wicks water in all directions by osmosis. Splashing bounces up.
