When they are connected in parallel, the equivalent resistance is 4.07 Ohms. What are (a) the smaller resistance and (b) the larger resistance of these two resistors? When two resistors, R1 and R2, are in series, they have...
An equivalent resistance correction coefficient kp of Ergun equation is proposed to eliminate the significant difference in the simulated results of flow field between REV scale and pore scale. Moreover, a formula is presented to predict the value of kp by the parameters of porous media ...
“The charges I shall have to pay to park weekly will equate to almost the equivalent of a year’s subscriptions to be a choir member.” equalize 同义词: level balance match equate (transitive) To make equal; to cause to correspond in amount or degree. || (obsolete, transitive) To...
For moderate salinities, the value of molality bi is approximately equal to the value of molarity ci (mol of species per L of H2O). Thus, Eq. (23) is equivalent to the following equation (Niemi et al., 2017): (24)ai=γb,ici,(i=1,…,naq) In general case, however, one would...
VOLUME-EQUIVALENT DIAMETERThe pressure drop versus airflow data for several types of grains were compiled and a grain specific generalized pressure drop versus airflow equation was developed. The equation predicted pressure drop as a function of airflow when porosity, moisture content and fine ...
Since gas hydrate exists in three different forms at the same time such as pore filling, particle support and separate stratification, the calculation method of hydrate saturation using traditional shaly sand formation interpretation models is equivalent to considering only the simple case that hydrate ...
Equivalent Length vs. Minor Pressure Head Loss in Pipe and Duct Components Minor pressure and head loss in pipes vs. equivalent length in tubes and duct systems. Fluid Flow - Entrance Length and Developed Flow The entrance length is the length in a tube or duct after an obstruction - until...
In this model, voltage is equivalent to blood pressure and current to blood flow. With systems models, the process is represented as an input/output relationship—transforming an input signal or stimulus into a response. Figure 5.2 shows a model of the neural pathways that mediate the vergence ...
The Ergun equation systematically underestimates the pressure drop for beds of non-spherical particles. In Eq. (2), the equivalent volume diameter, dp, of a particle of arbitrary shape is defined as the diameter of a sphere having the same volume as the particle: (4)dp=6Vpπ1/3 The ...
Since gas hydrate exists in three different forms at the same time such as pore filling, particle support and separate stratification, the calculation method of hydrate saturation using traditional shaly sand formation interpretation models is equivalent to considering only the simple case that hydrate ...
