Convert Nm3/h to m3/h
Hello,
for my labwork, I need to express Nm3/h to m3/h. I know that the N of Nm3 stands for Normal, meaning standard temperature and pressure. So, I have used the following expression to calculate the volume in m3. V2 = P1*V1*T2/(T1*P2) My manometer gives a flow rate of 15 Nm3/h. So, by using the standard conditions (T1=273.15 K, P1=101325 Pa), I have found for different pressure at 298.15 K the following results : P2(Pa) 200000 400000 600000 T2=298.15K V1=15m3 V2 (m3) 8.3 4.15 2.77 for example ,V2=101325*15*298.15/(200000*273.15) I don't understand why the volume decreases when the pressure increases. could you help me please?
