flow conversion
(OP)
i want to convert 1356 NM^3/Hr to M^3/Hr.it is very confusing, what is full form of NM^3/Hr. if any one have solution answer me.
cheers,

RE: flow conversion
Nominal meters cubed is volume at stated pressure.
http://en.wikipedia.org/wiki/Normal_cubic_metre
Effectively they are the same at same pressure
RE: flow conversion
Actual volume per unit time is the volume flow rate at actual conditions.
Mass flow rate is not dependent on pressure and temperature so:
m(dot) = q * ρ = qactual*ρactual=qnormal*ρstandard
So if you have volume flow rate at standard conditions (which is what is almost always reported) and you want a velocity you have to convert to volume flow rate at actual conditions. The equation above shows you how:
qactual=qnormal*ρstandard / ρactual
Then divide by flow area to get velocity. Always remember that any flow at normal or standard conditions is imaginary and not useful for very many engineering calculations.
