Well, what exactly do you want to know? The formula ΔP = ρ g h says it all.sandeep singh said:Homework Statement
i want to know about the variation in pressure according to varo=ious depth in different water bodies like for river, lake, stream, and all with the possibility of having fresh water or salty water. (not talking about oceans) may be shore of a sea will also work.
Homework Equations
pressure in water is rho * h * g
kindly help if you have any helpful data or solutions. Thanks in advance.
There is a slight change in pressure when water is flowing, but for practical purposes, like trying to open a car door when the car is submerged, this makes little difference.sandeep singh said:i wanted to know how much pressure a car (specially door) experience when it fell off into the river or lake in an accident. As a person trapped inside is not able to push the door open due to this pressure. and i m even confused how to know it exactly as it varies with running water and steady water also...
Yes, this formula still works. But pressure is not the only thing you are looking for here.sandeep singh said:thanks for your reply.. so do i still use the same equation (delta p) = (rho) * g * h ...for calculation of the exact pressure experienced by the car door for my project...??
For still water that will work fine.sandeep singh said:thanks for your reply.. so do i still use the same equation (delta p) = (rho) * g * h ...for calculation of the exact pressure experienced by the car door for my project...??
The pressure variation with depth in various water bodies is the change in pressure as you go deeper into a body of water. This change in pressure is caused by the weight of the water above pushing down on the water below.
The pressure variation with depth in water bodies is affected by several factors, including the density of the water, the depth of the water, and the gravitational pull of the Earth. The deeper the water, the greater the pressure, and the denser the water, the greater the pressure. The gravitational pull also plays a role in the pressure variation, as it pulls the water downwards and increases the pressure.
The pressure variation with depth can have a significant impact on marine life. As animals and plants descend deeper into the water, the pressure increases, which can affect their bodies and behavior. Some species have adaptations to withstand high pressures, while others may not be able to survive at certain depths.
Scientists use a variety of tools to measure pressure variation with depth in water bodies. These include pressure sensors, depth gauges, and underwater vehicles equipped with pressure sensors. Sonar technology is also commonly used to map the pressure changes in underwater environments.
The pressure variation with depth in water bodies can have a significant impact on underwater structures, such as submarines, pipelines, and offshore platforms. These structures must be designed to withstand the high pressure at certain depths and may require specialized materials and construction techniques. Failure to properly account for pressure variation can result in structural damage or collapse.
