What is thermodynamic properties of air?
Thermophysical properties of air: Boiling temperature (at 1 bara): 78.8 K = -194.4 °C = -317.8 °F. Bulk modulus elasticity: 1.01325 x 105 Pa or N/m. Condensation temperature (at 1 bara): 81.8 K = -191.4 °C = -312.5 °F.
What is CP and CV of air?
The nominal values used for air at 300 K are CP = 1.00 kJ/kg. K, Cv = 0.718 kJ/kg. We find that choosing values of specific heat capacities at the average temperature of each process gives results with reasonable accuracy (within around 1%). …
What is thermal conductivity of air?
Thermal conductivity of Air is 0.025 W/(m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.
What is the thermal capacity of air?
Table of specific heat capacities
| Substance | Phase | Isobaric mass heat capacity cP J⋅g−1⋅K−1 |
|---|---|---|
| Air (Sea level, dry, 0 °C (273.15 K)) | gas | 1.0035 |
| Air (typical room conditionsA) | gas | 1.012 |
| Aluminium | solid | 0.897 |
What are the steam tables?
Steam tables are defined as the thermodynamic data that contain the properties of water or steam. These data are commonly used by engineers. It is normally used to obtain the following properties using steam pressure for saturated steam temperature and saturated temperature for saturated steam pressure.
What is the CP value of air?
1.005 kJ/kg K
The specific heat of air at constant pressure is 1.005 kJ/kg K. and the specific heat of air at constant volume is 0.718 kJ/kg K. .
What is the K value for air?
1.4
In most of the cases, K is referred to as the ratio of specific heats. Here, the value of K for air is 1.4. In some other instances, K stands for Coulomb’s Constant, whose value is well accepted to be approximately 8.99 x 109 N in air.
Is air an ideal gas?
For any given gas, when the temperature is high and pressure is low, that gas behaves like an ideal gas. Hence, we can say that air can behave like an ideal gas.
