Calculation: Diameter of the suction line at a dosing pump

pBeh Absolute pressure in the chemical tank [bar] (sea level = 1)
pDampf Vapour pressure of dosing agent at valve inlet temperature [bar] (Water at 20 °C = 0.023)
HSaug Pump suction height [m] (>0 at feed, <0 at suction)
Density Chemical density [kg/dm3] (Water = 1.0)
Q Pump delivery capacity [l/h]
F Pump stroke frequency [stroke/min]
L Length of suction line [m]
decimal places
NPSHa Net Positive Suction Head, available [bar]
d Minimum diameter of suction line [mm]

Any evaluations and results are based on rough calculations and have to be checked by your own. No guarantee.
