What is the specific volume of nitrogen?
Table of common specific volumes
| Substance name | Density | Specific volume |
|---|---|---|
| (kg/m3) | (m3/kg) | |
| Hydrogen | 0.0899 | 11.12 |
| Methane | 0.717 | 1.39 |
| Nitrogen | 1.25 | 0.799 |
What is CP and CV of nitrogen?
If C p and C V denotes the specific heat of nitrogen at constant pressure and constant volume respectively, then A. c p – c v =28 RB.
What is the volume fraction of nitrogen in the air?
78 vol%
Air is a mixture of several gases, where the two most dominant components in dry air are 21 vol% oxygen and 78 vol% nitrogen.
What is the nitrogen content of air?
approximately 78 percent
The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
What is percentage of nitrogen in air?
78 percent
78 percent of the air we breathe in is nitrogen gas.
How do you calculate specific volume of dry air?
ν = V / m where V is volume and m is mass. ν = 1 /ρ = ρ-1 where ρ is density. ν = RT / PM = RT / P where R is the ideal gas constant, T is temperature, P is pressure, and M is the molarity.
What is specific volume of gas?
For ideal gases, specific volume is the gas constant (0.08206 L (atm) / mol (K)) represented by R, multiplied by temperature (T), and divided by pressure (P) times the molar mass (M). v = RT / PM. Common units for specific volume are (m3/kg), but cubic centimeter per gram (cm3/g) is also used.
What is the specific heat capacity of nitrogen gas?
1.04 J/g K.
Specific heat of Nitrogen is 1.04 J/g K. Latent Heat of Fusion of Nitrogen is 0.3604 kJ/mol.
How do you calculate nitrogen CV?
(Given R = 8.3 J mol^-1 K^-1 ; also, for a diatomic gas, C_v = 5/ 2 R.
What is the composition of dry air?
Standard Dry Air is made up of nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon. It does not include water vapor because the amount of vapor changes based on humidity and temperature. Because air masses are constantly moving, Standard Dry Air is not accurate everywhere at once.
What is the percentage of nitrogen in air?
What is the specific volume of dry air in kg?
There is 4.6 kg of dry air. Then what is the specific volume? Specific volume = 5 m 3 / 4.6 kg Constant specific volume lines on psychrometric chart are inclined and they have a negative slope. Constant specific volume lines on psychrometric chart have been marked on following psychrometric chart figure.
Air is a mixture of several gases, where the two most dominant components in dry air are 21 vol% oxygen and 78 vol% nitrogen.
What is the molar mass of nitrogen in air?
Engineering ToolBox – Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Sponsored Links. Air is a mixture of several gases, where the two most dominant components in dry air are 21 vol% oxygen and 78 vol% nitrogen. Oxygen has a molar mass of 15.9994 g/mol and nitrogen has a molar mass of 14.0067 g/mol.
What is the specific gravity of liquid nitrogen?
Liquid nitrogen is used to freeze foods, to preserve whole blood and other biologicals, and as a coolant. Nitrogen is nontoxic and noncombustible, but it may cause asphyxiation by displacement of air. Specific Gravity, air = 1: 0.967: Specific Volume (ft 3 /lb, m 3 /kg) 13.98, 0.872: Density of liquid at atmospheric pressure (lb/ft 3, kg/m 3)
