The water pressure at the bottom of a lake primarily depends on the depth of the water above that point and the density of the water. As depth increases, the pressure increases due to the weight of the water above exerting force downwards. Additionally, factors like temperature and salinity can affect water density, thereby influencing pressure. The formula for calculating pressure at a given depth is ( P = \rho g h ), where ( P ) is pressure, ( \rho ) is the water density, ( g ) is the acceleration due to gravity, and ( h ) is the depth.
What else can I help you with?
Why does a dam at the end of a lake need to be wider at the bottom?
Because water pressure is greater near the surface of the water
Explain why dams on deep lakes should be thicker at the bottom than near the top?
Water pressure increases with depth. So in a deep lake the bottom of the damn needs to be thicker to accommodate the greater water pressure.
What does the depth of the water?
The depth of water in a lake, tank, ocean - or whatever contains it will determine the hydro-static pressure at the bottom. It will also significantly influence the temperature and amount of light and thus the ecosystem at the bottom of the water.
What does lake bottom mean?
The bottom of a lake or the lake bed or a depression forming the ground under a body of water.
What is the absolute pressure at the bottom of a lake that is 25 m deep?
10 m is equivalent to about 1 ATM (1 atmosphere) SO 25 m is equal to 2.5 ATM's absolute pressure would include the 2.5 ATM's plus 1 ATM (standard for sea level) so the answer would be 3.5 ATM's or about 35000 Pa (pascals)
How many gallons of water are in a 30 acre lake?
The answer will depend on how deep the lake is!
Which has more pressure The bottom of a lake 7M deep or the bottom of a river 2M shallower than the lake but holds greater volume of water?
This is clearly homework and Wiki will not help you cheat so it is time to get out your notes or book and think about this question. Get to work.
When water is going to freeze on the surface then what is the temperature of bottom in water?
Not really possible to say. However, deep lakes tend to have bottom temperatures closely approximating average underground temperatures, which depend on latitude. The water at the bottom of Table Rock Lake in southern Missouri, for example, is around 55 degrees year-round.
What does the depth of the water determine?
The depth of water in a lake, tank, ocean - or whatever contains it will determine the hydro-static pressure at the bottom. It will also significantly influence the temperature and amount of light and thus the ecosystem at the bottom of the water.
Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake?
The vapor pressure of a warm lake is higher than that of a cold lake because higher temperatures increase the kinetic energy of water molecules, causing them to evaporate more easily and increase the pressure of water vapor above the lake's surface.
Why is pressure at a bottom of an ocean much greater?
First of all, pressure is defined as force per unit area. In the case of a lake, the main force acting upon an object in the lake would be gravity, among others. At the surface of the lake, the pressure on the object would be the force that the column of air above exerts on it, divided by the area that the force is acting upon. On the other hand, the pressure on the object at the bottom of a lake would be the force of the column of air PLUS the force of the lake water above, divided by the area that the force is acting upon. Therefore, the pressure must be greater at the bottom of the lake.
How much money does it cost to clean lake water?
That will depend dramatically on what the water is contaminated with and if the contamination was also in the sediments and/or the groundwater system of the lake.
