Eurotubi Pressfitting System - Technical Guide ... - Damstahl

where:
ΣZ
Z
is the result of Z 1 + Z 2 + ... + Z n
is the pressure drop of the single fitting expressed in mbar
As well, the following formula is used to calculate the pressure drop of the single fitting
Z = ξ • ρ • v 2 /2
where:
ξ is the coefficient, which depends on the fitting type
ρ is the fluid density expressed in Kg/m3
v is the fluid speed expressed in m/s
For a practical calculation of pressure drops it is possible to refer to the following tables.

14. CHEMICAL COMPATIBILITY OF EUROTUBI PRESSFITTING SYSTEMS
Note. The compatibility values stated are generic. Liquids for food use other than water can not be included
since pressfitting systems are not suitable for these elements as stagnation may form in correspondence
with the joints. For more information please contact the Eurotubi Technical Department.
