What is the importance of fluid pressure in dams?
Pressure=density*gravity*height In water density and gravity are constant, therefore pressure only changes with height. The dam would need to be thicker at the bottom than at the the top to withstand the higher pressure at the base of the structure.
How does density of an object relate to the pressure it exerts?
The further down you go the more pressure is exerted upon that point by the sum of the weight ( gravity and density) of the substance (usually water) above that point (the height or depth). For example, if their where say more argon than there is now in the atmosphere the barometric pressure would be higher when ignoring the changes in pressure due to weather.
How do you find altitude pressure?
Pressure= Force/Area Pressure of a Liquid is density times gravity times height
What affects the temperature and climate of a region?
The temperature of a region is affected by the height of the place, how slanted the place is, air pressure and air density.
How can one Calculate the PSI of water in river based off velocity of the river?
You can't... Pressure is influenced by many other factors, temperature and density for example... Also the height is a factor (atmospheric pressure)
Why does the height of the column in a barometer changes as atmospheric pressure changes?
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
How does upward pressure find?
pressure =force/ area pressure of a liquid is density time height.
What is the formula to calculate pressure?
Force over Area= Pressure

Why does the height of the liquid column in a barometer changes as atmospheric pressure changes?
Pressure tendancies measure short term weather. The mercury in a barometer will rise with atmospheric pressure denoting fairer weather and a fall in barometric pressure warns of inclement weather.

How is pressure in the liquid related to depth?
Water pressure = height (depth) * density of substance * gravitational field strength
Explain hydrostatic pressure?
Hydrostatic pressure is the pressure exerted by a liquid when it is at rest. It is directly proportional to the height of a liquid column of uniform density.
Does absolute pressure in a liquid of constant density double when the depth is doubled?
No, the absolute pressure in a liquid of constant density would not double in this situation. This is because the atmospheric pressure is an independent variable, so it will keep the absolute pressure from doubling.
Water pressure as a function of depth and density?
p=(Rho)gh where p is pressure (Rho) is the density of water g is the force of gravity h is the height of the water column (depth)
What are the two factors that affect the pressure of the fluid?
For incompressible fluids it is its density and the height of the fluid over the point where the pressure needs to be determined
