Alongside
is a length of pipe with a flow of water through it which has
a velocity of 1m/s.
The gauges show the pressures
measured at several points. We can conclude that at 1 m/s:
 |
The pressure
drop of the filter is: 2 -1.8 = 0.2 bar
|
|
The pressure drop across the
valve is: 1.8 -1.7 = 0.1 bar
|
EXERCISE
: If
the velocity of the water were doubled, what would the gauges
placed at the outlet of the filter and at the outlet of the valve
then read?

: Refrepair Manual pages 516 to 530)
