Barometric Pressure or Atmospheric Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Atmospheric Pressure = Density*[g]*Height of Mercury Column
P_atm = ρ*[g]*h_m
This formula uses 1 Constants, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.
Density - (Measured in Kilogram per Cubic Meter) - Density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object.
Height of Mercury Column - (Measured in Meter) - Height of Mercury Column is defined as the height of the mercury column above the free surface.

STEP 1: Convert Input(s) to Base Unit

Density: 997.3 Kilogram per Cubic Meter --> 997.3 Kilogram per Cubic Meter No Conversion Required
Height of Mercury Column: 0.76 Meter --> 0.76 Meter No Conversion Required

What is Fluid Mechanics?

Fluid dynamics is “the branch of applied science that is concerned with the movement of liquids and gases”. It involves a wide range of applications such as calculating force & moments, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space, and modelling fission weapon detonation.

What is Viscosity?

Viscosity is a measure of a fluid’s resistance to flow. The SI unit of viscosity is poiseiulle (PI). Its other units are newton-second per square metre (N s m-2) or pascal-second (Pa s.). The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more slowly. Also, viscosity does not change as the amount of matter changes, therefore it is an intensive property.

How to Calculate Barometric Pressure or Atmospheric Pressure?

Barometric Pressure or Atmospheric Pressure calculator uses Atmospheric Pressure = Density*[g]*Height of Mercury Column to calculate the Atmospheric Pressure, The Barometric Pressure or Atmospheric Pressure formula is defined as the product of density of liquid filled in barometer, gravitational acceleration and height of mercury column above free surface. Atmospheric pressure is measured by a device called a barometer; thus, the atmospheric pressure is often referred to as the barometric pressure. The Italian Evangelista Torricelli (1608–1647) was the first to conclusively prove that the atmospheric pressure can be measured by inverting a mercury-filled tube into a mercury container that is open to the atmosphere. A frequently used pressure unit is the standard atmosphere, which is defined as the pressure produced by a column of mercury 760 mm in height at 0°C (𝜌 Hg = 13,595 kg/m3 ) under standard gravitational acceleration (g = 9.807 m/s2 ). If water instead of mercury were used to measure the standard atmospheric pressure, a water column of about 10.3 m would be needed. Atmospheric Pressure is denoted by P_atm symbol.

How to calculate Barometric Pressure or Atmospheric Pressure using this online calculator? To use this online calculator for Barometric Pressure or Atmospheric Pressure, enter Density (ρ) & Height of Mercury Column (h_m) and hit the calculate button. Here is how the Barometric Pressure or Atmospheric Pressure calculation can be explained with given input values -> 7432.931 = 997.3*[g]*0.76.
