## Gauge Pressure given Absolute Pressure Solution

STEP 0: Pre-Calculation Summary
Formula Used
Gauge Pressure = Absolute Pressure-Atmospheric Pressure
Pg = Pabs-Patm
This formula uses 3 Variables
Variables Used
Gauge Pressure - (Measured in Pascal) - Gauge Pressure is the amount by which the pressure measured in a fluid exceeds that of the atmosphere.
Absolute Pressure - (Measured in Pascal) - Absolute Pressure is labeled when any pressure is detected above the absolute zero of pressure.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.
STEP 1: Convert Input(s) to Base Unit
Absolute Pressure: 100000 Pascal --> 100000 Pascal No Conversion Required
Atmospheric Pressure: 101325 Pascal --> 101325 Pascal No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pg = Pabs-Patm --> 100000-101325
Evaluating ... ...
Pg = -1325
STEP 3: Convert Result to Output's Unit
-1325 Pascal --> No Conversion Required
-1325 Pascal <-- Gauge Pressure

## < 7 Pressure and its Measurement Calculators

Force at Point 1 using Pascal's Law
Force at Point 1 = Force at Point 2*(Area at Point 1/Area at Point 2)
Force at Point 2 using Pascal's Law
Force at Point 2 = Force at Point 1*(Area at Point 2/Area at Point 1)
Area at Point 1 using Pascal's Law
Area at Point 1 = Area at Point 2*(Force at Point 1/Force at Point 2)
Area at Point 2 using Pascal's Law
Area at Point 2 = Area at Point 1*(Force at Point 2/Force at Point 1)
Barometric Pressure or Atmospheric Pressure
Atmospheric Pressure = Density*[g]*Height of Mercury Column
Vacuum Pressure given Atmospheric Pressure
Vacuum Pressure = Atmospheric Pressure-Absolute Pressure
Gauge Pressure given Absolute Pressure

## 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 Gauge Pressure given Absolute Pressure?

Gauge Pressure given Absolute Pressure calculator uses Gauge Pressure = Absolute Pressure-Atmospheric Pressure to calculate the Gauge Pressure, The Gauge Pressure given Absolute Pressure formula is defined as the additional pressure in any system relative to the atmospheric pressure, and is equal to the difference between the absolute and atmospheric pressure while also being zero-referenced against the ambient air pressure.
