The linear relationship is the pressure propagation equation (or pressure equation). However, these studies do not arrive at the same constant coefficient representing the linear relationship. The purpose of this study is to find the constant coefficient for the pressure propagation equation. The ...
aIn this equation, q is the turbine flow rate; p0 represents the static pressure of the water column, p is the pressure at the turbine admission and pf is the pressure loss due to friction in the conduit. Tw is a characteristic constant of the conduit which is usually known as the water...
Equation of state: (20-4)Pρ=ZRMWT which can also be written as: (20-4a) P = C Wherenvaries from 0 →∞;n=0,P=C(constant pressure process);n= 1,T=C(constant temperature process);n=γ(γ=CpCv),S=C(constant entropy process);n= ∞,V=C(constant volume process). ...
pressure amplitude, stress ratio level and density on the strain evolution. Second, new constitutive functions for an existing Bounding Surface Plasticity model are proposed in the paper. They are intended
where p is the average pressure on the inside surfaces of the container, kB=1.381×10−23JK−1 is Boltzmann's constant, and T is the absolute temperature. Equation (1.21) is the molecule-based version of the perfect gas law. It is valid when attractive forces between the molecules are...
The solution of Equation given below for a constant volume process is also not difficult. The work done in a constant volume process is the product of the volume and the change in pressure. In addition to gases, Equation 1-45 also applies to liquids. The power requirement for pumps that ...

the equation of non-stationary heat conduction is solved. The conjugation of temperature fields in a gas and a solid is carried out using an iterative procedure. In the calculations, the geometrical parameters of the cavity, the density of the energy supply, the initial pressure, and the compos...
a. Trickle-bed reactor: The pressure drop in the trickle-bed reactor is evaluated using the correlation of Larkins et al. (eq. (3.390)). However, at first we have to evaluate the single-phase pressure drop for the gas and the liquid. Using the Ergun equation (3.449), the pressure drop...
In the case of constant pressure injection, filling times are usually predicted by using the integral form of Darcy's law, but they are often off the reality. A solution is proposed here by considering that the flow rate expected during the process cannot always be provided by the injection ...
