How do you get the percentage of atmosphere above a height given in km and then how do you get the pressure for the height in mb?

To find the percentage of atmosphere above a certain height in kilometers, you can use the barometric formula to calculate the pressure at that height. Then, you can simply divide the pressure at the given height by the pressure at sea level (1013.25 mb) and multiply by 100 to get the percentage of atmosphere above that height.


What is the formula for calculating the water pressure height based on the water pressure and the height of the water column?

The formula for calculating water pressure height is: Pressure Density of water x Gravity x Height.


How does atmosphere pressure with height in the atmosphere?

Generally, atmospheric pressure is greatest at ground level, because you are at the bottom of the 25 mile thick atmosphere of earth. Greatest water pressure in a swimming pool is at the bottom, too. As you go up into the atmosphere, the pressure tends to decrease.


A decrease in the height of a column in a mercury barometer means that?

there is a decrease in atmospheric pressure. Atmospheric pressure is directly proportional to the height of the mercury column in a barometer. When the height decreases, it indicates that the pressure in the atmosphere is lower.


What is the water pressure formula and how can it be used to calculate the pressure in a given system?

The water pressure formula is P gh, where P is the pressure, is the density of water, g is the acceleration due to gravity, and h is the height of the water column. This formula can be used to calculate the pressure in a given system by plugging in the values for density, gravity, and height of the water column.


At approximately what height in the atmosphere would the atmospheric pressure be at 1.0 millibars?

The atmospheric pressure of 1.0 millibars is typically found at an altitude of about 50 kilometers above the Earth's surface. At this height, the pressure is very low, and it is considered to be part of the upper atmosphere or exosphere.


When the height of the mercury in a barometer is 29.92 inches the barometric pressure is?

When the height of the mercury in a barometer is 29.92 inches, the barometric pressure is equivalent to standard atmospheric pressure at sea level, which is 1013.25 millibars or 14.7 pounds per square inch (psi).


Weather element that always decreases with increasing height?

Pressure always decreases with height. This is because atmospheric pressure is just a measure of how much air is weighing down. So the higher you go in the atmosphere, the less air is above you (more of it is below you) and the lower the pressure will be.


What is the formula to calculate pressure?

Force over Area= Pressure


What is the formula for calculating the pressure (p) in a fluid system, where pressure is equal to the height (h) of the fluid column divided by the specific gravity of the fluid () ?

The formula for calculating pressure (p) in a fluid system is: p h / .


How to calculate water pressure from flow rate?

To calculate water pressure from flow rate, you can use the formula: Pressure Flow Rate x 0.433 x Height. This formula takes into account the flow rate of the water in gallons per minute and the height of the water column in feet. By multiplying the flow rate by 0.433 and the height, you can determine the water pressure in pounds per square inch (psi).


How much is 1 atmosphere?

One atmosphere is approximately equal to the pressure exerted by a column of mercury 760 mm (29.92 inches) in height. This pressure is used as a reference point for other pressure measurements.
