Equations describing the affect of cohesion on standpipe flow and a model predicting the onset of void formation are presented. This work also develops the relationship between the standpipe slope angle and the ratio of the solid-contact pressure against the standpipe wall to the solid-contact ...
Gas viscosity and density vary significantly with pressure and therefore the assumptions of Equation 6-76 are not satisfied for gas systems, i.e., compressible fluids. In order to develop the proper mathematical function for describing the flow of compressible fluids in the reservoir, the following...
In addition, it was also found that the relationship of pressure with flow rate could only be described by using a polynomial function, instead of the classic binomial and exponential functions. All the curves related to pressure and flow rate were of strong nonlinearity. Furthermore, an ...
I now the flow of natural gas through an orifice will be the same on both sides with a little pressure differential. But if i have 900 PSIG at 4mmscfd measured upstream and the other side of the valve or orifice is attached to a pipe to atmosphere. Is the flow going to be higher on...
The results showed that water altered the gas desorption rate in coal, causing fluctuating attenuation of the desorption rate of a water-injected coal sample (WCS). Under the same adsorption equilibrium pressure, the relationship between the desorption rate of the WCS and the non-water-injected ...

Experimental and Modeling Studies for Gas-liquid Two-phase Flow at High Pressure Conditions Experimental and model studies were performed on two-phase flow behavior at high-pressure conditions. The experiments were conducted using nitrogen and wat... A Plat,A Norio,M Ryo,... - 《Journal of the...
However, the model predicts the state variables only at the particular (trained) ambient temperature and pressure, as variations of ambient temperature and pressure are not considered in the training of DeepONet. The model also does not predict the parameters of the engine model. While the model...
The ideal gas law demonstrates the relationship between the pressure (P), volume (V) and temperature (T) of an ideal gas. Eq. (1.17) is an expression of the ideal gas law: Equation 1.17: Ideal gas law (1.17)PV=nRT Where: P: Pressure of the gas (pound per square inch (psi), atm...
In dealing with gases at a very low pressure, the ideal gas relationship is a convenient and generally satisfactory tool. At higher pressures, the use of the ideal gas equation-of-state may lead to errors as great as 500%, as compared to errors of 2–3% at atmospheric pressure. Basically...
