Gauge Pressure given Absolute Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gauge Pressure = Absolute Pressure-Atmospheric Pressure
P_g = P_abs-P_atm
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

P_g = P_abs-P_atm --> 100000-101325

Evaluating ... ...

P_g = -1325

STEP 3: Convert Result to Output's Unit

-1325 Pascal --> No Conversion Required

FINAL ANSWER

-1325 Pascal <-- Gauge Pressure

Force at Point 1 using Pascal's Law

Go Force at Point 1 = Force at Point 2*(Area at Point 1/Area at Point 2)

Force at Point 2 using Pascal's Law

Go Force at Point 2 = Force at Point 1*(Area at Point 2/Area at Point 1)

Area at Point 1 using Pascal's Law

Go Area at Point 1 = Area at Point 2*(Force at Point 1/Force at Point 2)

Area at Point 2 using Pascal's Law

Go Area at Point 2 = Area at Point 1*(Force at Point 2/Force at Point 1)

Barometric Pressure or Atmospheric Pressure

Go Atmospheric Pressure = Density*[g]*Height of Mercury Column

Force acting on Surface

Go Force acting on Surface = Pressure Intensity*Area of Surface

Vacuum Pressure given Atmospheric 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. Gauge Pressure is denoted by P_g symbol.
