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 Vacuum Pressure given Atmospheric Pressure?
Vacuum Pressure given Atmospheric Pressure calculator uses Vacuum Pressure = Atmospheric Pressure-Absolute Pressure to calculate the Vacuum Pressure, The Vacuum Pressure given Atmospheric Pressure formula is defined as a pressure less than the local atmospheric pressure. It is defined as the difference between the local atmospheric pressure and the point of measurement. Vacuum Pressure is denoted by P_{vacuum} symbol.
How to calculate Vacuum Pressure given Atmospheric Pressure using this online calculator? To use this online calculator for Vacuum Pressure given Atmospheric Pressure, enter Atmospheric Pressure (P_{atm}) & Absolute Pressure (P_{abs}) and hit the calculate button. Here is how the Vacuum Pressure given Atmospheric Pressure calculation can be explained with given input values -> 1325 = 101325-100000.
