How do you calibrate water tank?

1 - cross section of of the tank and the height can be calibrated. 2 - With a gallon of fluid in the reservoir was built and calibrated.

Why are the water tanks elevated?

So you can use gravity rather then a pump to get water out of them.

How is rain water collected?

rain water collected from roofs of houses,making tanks,etc.

Why are water towers elevated so high while petroleum tanks are on the ground?

Because water towers are a cheap, reliable way of generating enough pressure to get the water into your house--not an issue with petroleum tanks. If you didn't have towers you'd have to use pumps, and buying enough pumps to meet peak demand would be prohibitively expensive for most towns. Towers simplify matters. You pump water up at a steady rate and gravity does all the work getting it down. Since the pressure is a function of the height of the column of water inside the tower, and since the height of that column doesn't diminish appreciably until the tank is virtually empty, the pressure stays steady regardless of fluctuations in supply and/or demand.

How is a hydro electric power station built?

A dam is built, normally across a river but sometimes across a lake or even the sea, in a suitable place. Anyway, once the dam is built, water cannot pass through so it builds up on one side - so that you have a dam with a high water level on one side and no water on the other. There are passages built into the bottom of the dam which contain turbines, and once the water level reaches a sufficient height these passages are opened and water can pass through from the 'high level' side to the 'no water' side (obviously). As the water goes through the passages it spins the turbines which in turn spin electrical generators, creating electricity.

Why the water height is held constant in the tank?

Aboveground water tanks come with airtight lids that do not allow pollutants to enter the tank. Besides, keeping water storage tanks at height ensures that they are free from rats, mice, and other insects that can easily contaminate water if the tank is kept on the ground. Hope this helped

How do you join 2 plastic water tanks to make them work as one?

To join 2 plastic water tanks, ensure they are the same size and type. Use a PVC or polyethylene pipe and fittings to connect them at the bottom or sides. Seal the connection with a waterproof adhesive or silicone to prevent leaks. Make sure the tanks are securely fastened in place to avoid any movement or instability.

Can water tanks explode from well water?

I've never heard of that. Most tanks are built to withstand at least 150 psi and most domestic pumps will not reach that limit.

Can you put tap water in frog tanks?

Of course. You should always read about your frog type before attempting to, but frogs can survive with tap water.

How does a submarine floats then sinks then floats?

It is a matter of buoyancy. There are large tanks that can be filled with sea water or with air. To submerge they pump the air into compressed tanks and the water fills it up sinking the sub. When they want to go back up, they blow the water out using the compressed air.
