What is meaning of Nm3 HR?

What does Nm3/hr mean? Normal Meter Cubed per Hour. Unit used to measure gas flow rate. The ‘Normal’ refers to normal conditions of 0degC and 1 atm (standard atmosphere = 101.325 kPa) – for practicle purposes this is rounded to 1 bar.

Also, How much does a cubic foot of hydrogen weigh?

In Imperial or US customary measurement system, the density is equal to 0.0051 pound per cubic foot [lb/ft³], or 0.0000474 ounce per cubic inch [oz/inch³] . Hydrogen is a colorless, odorless gas.

Accordingly, How do you convert Nm3 hr to CFM?

How Do You Convert NM3/h to CFM?

What is the difference between Nm3 HR and m3 HR? NM3 and M3 are the units that are used in measuring the volume of liquids, solids and gases. … NM3 is the value that a matter whether solid, liquid or gas of a constant mass occupies under normal or standard conditions and M3 is volume that it will occupy at the prevailing conditions of temperature and pressure.

What is the difference between Nm3 HR and Sm3 HR?

The conversion from Sm3 to Nm3:

Temperature is entered in K; 273.16 is temperature of tripple point of water. Interpretation: Gas of certian weight takes under normal conditions volume of 7,32% smaller than under standard conditions. Therefore 1 Nm3 contains 7.32% more gas than 1Sm3.

What does 1 cubic meter of liquid hydrogen weigh?

Hydrogen, liquid weighs 0.07 gram per cubic centimeter or 70 kilogram per cubic meter, i.e. density of hydrogen, liquid is equal to 70 kg/m³; at -259.16°C (-434.488°F or 13.99K) at standard atmospheric pressure.

How do you calculate hydrogen pressure?

To find the mole count, divide the mass in grams by 2.016. For example, if the mass of the hydrogen gas is 0.5 grams, then n equals 0.2480 moles. Convert the temperature T into Kelvin units by adding 273.15 to the temperature in Celsius. Use the ideal gas equation (PV=nRT) to solve for pressure.

How many moles are in 1 kg of hydrogen?

The atomic mass of hydrogen is 1 g/mole. To make up 1 kilogram or 1000 g of hydrogen element, 1000 moles of hydrogen is required. Each mole has a Avogadro’s number of atoms or atoms. Thus, 1 kg hydrogen element or 1000 moles of hydrogen have atoms (or 1000 times the Avogadro’s number).

How do you convert NM3 to KG?

Nm³ is volume at standard temperature and pressure, that is, 1 atmosphere and 20 deg C according to some. The density of propane may not vary much between 20 or 25 deg. C. So volume times density gives weight, that is 1* 493 = 493 kg/h.

How many kWh does it take to produce 1 kg of hydrogen?

1 kg of hydrogen contains 33.33 kWh of usable energy, whereas petrol and diesel only hold about 12 kWh/kg (see www.h2data.de). In terms of volumetric energy density however, hydrogen is outperformed by liquid fuels.
