DETERMINING THE INTERNAL DIAMETER
HOW TO DETERMINE THE INTERNAL DIAMETER (I.D.) OF HOSES.

How to determine the internal diameter (I.D.) of hoses
Delivery (l/min)
Flow velocity (m/sec)
ND (mm)
EXAMPLE:
Given a flow rate of P= 60 l/min and a velocity V= 5 m/sec,
the nominal size will be I.D.: DN= 16.
Resistances to flow are not considered.
