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.
How to calculate Gauge Pressure given Absolute Pressure using this online calculator? To use this online calculator for Gauge Pressure given Absolute Pressure, enter Absolute Pressure (P_{abs}) & Atmospheric Pressure (P_{atm}) and hit the calculate button. Here is how the Gauge Pressure given Absolute Pressure calculation can be explained with given input values -> -1325 = 100000-101325.
