For an Ideal gas(steam), the compressibility factor is obviously unity under all conditions whereas for real gas(steam), the compressibility factor may be less or more than unity based on the actual conditions. With best regards, elavazhgan.
high compressibility of gas is very useful to us. due to this property, gases can be easily liquified into very small volumes and can be used in our homes and in other works. eg. LPG, CNG.
In the steam drum, where steam exits and flows to the superheaters.
The steam required for steam tracing is calculated on the basis of the amount of heat transfer that is required or the temperature that you want to maintain with the help of steam. It also depends on the pipe material through which the steam is passing,the condition of the steam that whether it is saturated or superheated etc. Overall heat transfer cofficient is calculated considering all the factors like fouling or scaling,inside and outside dia. , surface area etc. After calculating the amount of heat to be transferred, the requirement of rate of steam is calculated. Generally, Low pressure steam is used as it has got more latent/Sensible heat as compared to MP or Superheated steam.

If you use saturated steam, the main source of the heat is provided by the condensation of the steam at a constant temperature. The energy provided by the condensing steam is significantly more than what you can get from just changing the temperature of superheated steam. When the temperature remains constant, design calculations are also a lot easier; the temperatures stay the same (or almost the same) for the steam along the entire run and the pressure stays the same (or almost the same).
The compressibility of Jetfuel is 0.88x10-9 m2/N

At this condition the compressibility factor will approximately be 1.03936 This shows that the air will behave al most as an ideal gas at very high pressure
z = 1 remember z = f(Tr,pr) Source: I'm a ChE!
The super compressibility factor of natural gas depends on its composition, temperature, and pressure conditions. It is typically used to correct for the non-ideal behavior of gas at high pressures and low temperatures to accurately predict its volume.
The compressibility factor for a gas mixture can be calculated by dividing the observed pressure of the gas mixture by the ideal gas pressure at the same temperature and volume. This ratio helps to account for the deviation of real gases from ideal gas behavior.

The compressibility factor, denoted as Z, is a measure of how much a real gas deviates from ideal gas behavior under given conditions of pressure, volume, and temperature. It is calculated as the ratio of the molar volume of the gas to the molar volume that would be predicted for an ideal gas at the same conditions. A compressibility factor of Z=1 indicates ideal gas behavior, while Z<1 or Z>1 indicates gas behaves as more or less ideal, respectively.
due to the lack of polarity in the hydrogen molecule as a result of it containing two of the same atom, and also the dominant force between the hydrogen molecules is the repulsion force, that tends to increase the volume

An ideal gas will have a volume that is inversely proportional to the pressure (assuming constant temperature). For example, if you double the pressure, the volume will be reduced to 1/2 the original volume. For real gases, the behavior is usually somewhat different. In some cases, if you double the pressure, the volume will reduce to LESS than 1/2 the original volume. This is due to the attraction between the molecules, and this phenomenon is called "supercompressibility".
The K-factor in steam blowing is a parameter used to determine the expansion characteristics of the steam during the process. It is calculated based on the initial and final pressures and temperatures of the steam, and helps ensure efficient cleaning of the system by controlling the thrust and velocity of the steam flow. A proper understanding and calculation of the K-factor are important for a successful and safe steam blowing operation.
