RE: Digest Number 1636

Dear Neeraj,

Further can I add that in case of water we take at the pump suction velocity as 0.8 m/sec, whereas in discharge we take the value as 1.75 m/sec( in case of SS pipes the velocity can further be taken upto 2 - 2.5 m/sec).

Basically it depends on the fluid handled, MOC of piping, pressure, friction factors...

Dear Neeraj,

Velocity can be calculated by Q =A.V
For industrial gases :
Normally in Main Lines : 4-8 m/sec
Main distribution Lines : 8 -10 m/sec
Nozzle end velocity :15-40 m/sec depending upon various limitation Best Reagrds

Dear Neeraj,

For water :

Branchs at hospital heating system : 0,5-0,7 m/sec Branchs at domestic heating system : 0,8-1 m/sec Branchs at rooms : 1-1,5 m/sec
Main distribution lines : 1,5-2,0 m/sec Main lines : 2,5-3,0 m/sec

Best Regards,

How do we decide the maximum velocity in a given diameter of pipe.
