m3/h is the unit for actual volumetric flowrate, this is the volumetric
flowrate at 6 bara, en t °C.
Nm3/h is the unit for volumetric flowrate at 1.013 bara and O°C(273 °K),
while Sm3/h (Standard m3/h) is used in the United Kingdom and is the
volmumetric flowrate at 1 bara and 15°C.
NPSH is the pressure above vapour pressure at the suction side of a pump. A stands for available, R stands for required by the pump.

Onderwerp: [PipingDesign] Tell me the difference
Hi to all,
As I am really new in Piping design, I have been facing some of very basic
problems like...
1) Difference between m3/hr, Nm3/hr, Sm3/hr [ what will be m3/hr, Nm3/hr &
Sm3/hr of a Comp air line of 100 NB size,at 6 Kg/cm2, temp 25 deg C],
2) What is NPSHR and NPSHA of pump (water), how it affacts the flow system.
If any one can answer that will be a gr8 pleasure.....
