24 Μαρ 2009 · 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.
07-03-2011, 08:29 PM. Re: Convert m3/h to either psi or bar. There is no conversion of m3/hr to psi. Using the electrical analogy - m3/hr is a measure flow which in the electrical analogy is equivalent to current (Amps) whereas psi is a measure of pressure which is eqivalent to electrical potential (Volts). As we know these are related through ...
30 Μαΐ 2010 · Re: convert Nm3/h to kg/h. Originally posted by Unregistered View Post. 7nm3/h nitrogen= kg/h. At "normal" conditions the molar volume of a gas is 22.414 L, so 7000 L is 312.3 mol of N2. Molar mass is 28.013 g/mol, so about 8.75 kg/h.
9 Ιαν 2008 · Volume of a gas depends on temperature and pressure, so you need to be sure the same temperature and pressure are assumed in both unit systems or make further conversion. Ignoring that. 254 m^3/h * 1h/60 min * (1 foot/0.3048 m)^3 = 149.5 cfm. Flag.
16 Απρ 2015 · With below equation you can convert NM3/hr to M3/hr which is flow measurement of gas under its process condition (T, P): Fn = gas Flow in normal condition. F = gas Flow under process condition. Fn (in Nm3/hr) = (273/ T+273) X (P+1.013/1.013) X F (in M3/hr ) If you want to get Mass flow on normal condition just multiply density on normal flow ...
12 Φεβ 2009 · It gives energy content per pound and per cubic foot, from which a density of 0.0485 lb/ft³ can be implied. If you have a mass flow of M kg/h, convert as. M kg/hr x 1 lb/0.4536 kg x 1 ft³/0.0485 lb = 45.5*M SCF/h. Remember that the 0.0485 factor can vary with gas supply. To get MMSCF, divide by 1 million.
Using the units above,w = wind speed in km/h, and r = revolutions per second, the above data is fit by. w = (10/3)* (r + 1) This equation predicts that for wind less than 3.3 km/h the tach won't turn at all due to friction (most wind sensors have a cut out speed) To con vert speed from km/h to m/s, divide by 3.6, thus.
1 Μαΐ 2009 · Well 3kg/s x 3600 s/h = 10800 kg/h. Now, all you need is the density of water. Cold water is about 1 kg/L or 1000 kg/m³. Hot water is a little less, and the value is temperature dependent. At 80 °C (the upper limit of my forced hot water system) the density of water is about 972 kg/m³, so 10800 kg/h x 1 m³/972 kg = 11.1 m³/h
16 Νοε 2022 · convert μmol CO2 m-2 s-1 to mg CO2-C m-2 hr-1. A mole of CO2 is 44 g (or 44 µg/µmol) and an hour is 3600 s/h. Multiply by both factors and cancel units. You wind up with your desired units. A mole of CO2 is 44 g (or 44 µg/µmol) and an hour is 3600 s/h. Multiply by both factors and cancel units.
9 Οκτ 2008 · At 1 atm., 0 °C, air density is around 1.3 kg/m³. Again, you need to decide worst case for safe design. Dynamic pressure is 0.5*1.3 kg/m³ * (7.5 m/s)² = 16.9 Pa. At area of 6.25 m² and drag coefficient of 1 (reasonable for a sign) total force at this wind speed is about 106 N. Please note that even a strong thunderstorm could generate ...
