Equations
Flow:
To convert fluid velocity into a volumetric flow rate. GPM = (ID2 x Feet/sec)/0.4084967
To convert volumetric flow rate into fluid velocity. Feet/sec = (GPM x 0.4084967)/ID2
Conductivity:
Conductivity = 1/Resistivity
1/Ohm = 1 Siemen = 1 mho
Measured conductivity = [(solution conductivity) x (electrode sectional area)]/ electrode separation Measured conductivity = Siemen/cm
