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)

Which more pressure formula of a lake 7 meters deep or the bottom of the river 2 meters shallower than the lake but hold greater volume of water?
Pressure depends on fluid depth, density, g, and surface pressure; not upon the volume.P at depth x = P0 + ( x ) ( density ) ( g )For P0 = 101000 Pa and d = 1025 kg per m^3 :P lake = ( 101000 N/m^2 ) + ( 7 m ) ( 1025 kg/m^3 ) ( 9.807 m/s^2 )P lake = ( 101000 N/m^2 ) + ( 70365 N/m^2 ) = 171365 N/m^2 = 171365 Pa
How does the water pressure 1m below the surface of the small pond compare with the water pressure 1m below the surface of a huge lake?
The pressure at the same depth in any container doesn't depend on the size of the container. The pressure one meter below the surface is the same in a pond, a lake, a swimming pool, the middle of the Pacific Ocean, or a bath-tub.
Why is there more pressure in the deep water?
Water pressure is caused by the weight of the water that is above it. At deeper levels there is more water above you. So there is more mass pressing on the water you are in. Pressure does not depend on the width, only on the depth. It is the same in a large basin as it is in an equally high pipe. On the surface there is also atmospheric pressure, because the atmosphere (the air) also has mass. This pressure must be added to the water pressure. It is roughly the same as 10 meters of water pressure. So, at 10 meters under water you have twice as much pressure than at the surface, at 20 meters three times as much, and so on. Seawater is heavier than freshwater, because there is salt in it. So the water pressure for every meter of depth in the sea is slightly higher than it is in a lake.
What factor determines the type of anchor used?
The type of bottom of the waterway, lake, etc. (PCOC Exam)
What will happen if the density of surface water in the lake does not change?
The water will be calm, because a change in density causes water to move and can also cause deep water currents
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.
How deep is okanagan lake?
very deep. it is said that the bottom of the lake has still not been found the depth is endless.
What is the temperature at the bottom of most lakes?
Depends on how deep the lake is, and the climate where the lake is located.
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.
What water temperature would be at the bottom of a deep lake?
Above 0 0C
A man has drowned in the middle of the lake which is almost twenty feet deep and is lying at the bottom of the lake he did not swim there nor was he carried there how did he get to the middle of the?
He flied there by plane, jumped with parachute which didn't opened and ended up on the bottom of the lake.
Fewer organisms live at the bottom of a deep lake because of the lack of what?
Because of lack of oxygen and sunlight.
A man has drowned in the middle of a lake which is almost 20 feet deep and is lying at the bottom of the lake He did not swim there nor was he carried How did he get to the middle of the lake and dr?
he was dropped, hence the sinking and the drowning
Explain why fewer plants are at the bottom of deep lakes?
colder temperatures and lower light levels limit the types of organisms that can live in deep lake waters
Would you expect to find many organisms living at the bottom of deep lake?
Yes, more than at the surfase.
Many examples of air pressure in daily life?
on an airplane, car on big hill, swimming in deep lake
How deep is cultus lake?
No one can determain this because the bottom has still not been found.
