Pitot Static Tube Online Calculation for Compressible and Incompressible Flow and Liquid

The Pitot Static Tube sometimes referred to as a Pitot Probe is a differential pressure device used as a flow meter for gases and liquids.  It uses a differential pressure principle for the measurement using the known or measured static pressure and total pressure differences know as the dynamic pressure. Pressure can be measured using a manometer or pressure transmitter. This flow metering device is also known as the Prandtl Tube. Examples of other variations of the probe are the averaging pitot probe - see examples

Explanation of the Static Pitot Tube calculator values

pt – total pressure
p – static pressure
pd – dynamic pressure
rho – density
kappa – isentropic coefficient
R – gas constant
t – temperatire
D – diameter
V- velocity
M- Mach number
c- sound speed
Q – volumetric flow rate
G – mass flow rate

The Pitot Static Tube Calculation can be used to calculate for

V- velocity
M- Mach Number
c- sound speed
Q – volumetric flow rate

To calculate these values the inputs need are as follows

FOR LIQUIDS  - Either pt and p – total pressure and static pressure or pd  - dynamic pressure rho- density. D – diameter is optional only if Q and G need to be calculated

FOR GASES – p- static pressure either pt – total pressure or pd- dynamic pressure kappa – isentropic coefficient R – gas constant Either T – temperature or rho –density D- diameter is optional and needed only if Q and G need to be calculated
