What is the water pressure at the bottom of a dam with a depth of 200 m?

In very round numbers, the pressure at the surface of the water due to the atmosphere above it
is 14.7 pounds per square inch, or about 100 kPa, and it increases by that amount with each
additional 10 meters of depth. So at the depth of 200 meters, the total is the pressure of the
atmosphere plus 20 times as much additional, or roughly 309 pounds per square inch (2100 kPa).
Notice that it doesn't matter whether you're talking about the bottom of Hoover Dam or the bottom
of a 200-meter soda-straw. The length and width of the pool are irrelevant. The only dimension that
contributes to the pressure is the depth.

That water in a glass has a weight of 2.4N the bottom of the glass has a area of 0.012m squaredwhat is the pressure exertid by the water on the bottom of the glass?
200 Pascals or 200 N/m sq.
What is the pressure at a depth of 200 feet?
104psi at 200 feet deep.
20BAR what is this measurement aquatic?
You question is not clear, but I think you mean to ask how deep in water is a pressure of 20 Bars. A bar is one atmosphere pressure which is about 10 meters of water depth. Since water is incompressible, the relationship is linear. 20 Bars is 200 meters depth.
What is the average depth of a water well?
The average depth of a water well can vary depending on factors such as location, geology, and water table levels. However, typical residential water wells in the United States range from 100 to 400 feet deep.
Is 200 psi of air the same as 200 psi of water?
Yes pressure is pressure
How much water pressure and vibration can the Invicta 8926 Men's Diving Watch resist?
The Invicta 8926 Men's Diving Watch is shock resistant and water resistant to a depth of 200 meters.
What was the depth of the water the Lusitania sank in?
Over 200 metres deep
What five distinct water masses result from density stratification?
to about 200 meters(600 feet)-surface water, to the main thermocline (depth varies with latitude) central water, to about 1,500 meters(5,000 feet) intermediate water, below intermediate water but not in contact with the bottom to about 4,000 meters(13,000 feet)-deep water, in contact with seafloor-bottom water
How many meters is equal to 20 bars?
You can't convert meters to bars, or bars to meters. The two are utterly incompatible. Meters is a unit of length, bars is a unit of pressure. if you mean depth of water then 20 bar = 200 metres (close)
What does it mean 200 meters for watches?
It is the depth that the watch can withstand if submerged in water (assuming you mean the subscript "200 meters" on a watch face). It can only be safe from leaking if you are submerged in less than 200 meters of water.
What is a fathometer?
Basic Concept: Fathometer surveys determine water depths by repeatedly transmitting seismic energy through the water column and recording the arrival time of the reflected energy from the water bottom. The instrument calculates the water depth from these data and prints a depth value as a continuous graphic profile. Most fathometers use a narrow bandwidth 200 kHz seismic signal. They provide accurate depth information, but very little information about the subbottom. Fathometers that use a lower frequency, e.g., 20 kHz, can detect reflections from subbottom interfaces such as the bottom of an infilled scour hole.
What is 200 meters in depth?
200 meters is 656.17 feet.
