As the pores in the medium are normally small and rate of flow of filtrate is low, laminar flow conditions are almost invariably obtained. So, the relationship between the superficial velocity u and the pressure drop can be described by Kozeny-Carman equation 150uL 1 2 p Dp2 2 3 3.4-2 ...
Water Flow in Pipes : The Relationship between Flow Rate and Pressure HeadBhatt, AmishHakkal, ChaitraKo, Hsufeng
The simple passive relationship between a given flow rate and the resulting pressure has been presented graphically by numerous investigators; diagrammatic examples of this relationship are presented in Figure 4(A) and (B). Although these figures are arbitrarily plotted with the flow (Q) on the ...
The flow of both Newtonian liquids and shear-thinning polymer solutions through fine mesh screens has been studied and results have been expressed as a loss coefficient-Reynolds number relationship. A single correlation covers both types of fluids over Reynolds numbers ranging from 10 5 to 5....
Relationship between ventilatory response and body temperature during prolonged submaximal exercise. We examined whether an increase in skin temperature or the rate of increase in core body temperature influences the relationship between minute ventilation...

Relationship between the optimum water content, maximum dry density, and addition rate of attapulgite This experiment performed the compaction test of specimens with different attapulgite content. The experimental results obtained the relationship between the maximum dry density, the optimum moisture content...
A theoretical relationship between mean ventricular pressure (.hivin.P) and mean ventricular outflow (.hivin.Q) was developed based on a model of the left ventricle with elastic-resistive properties. Using a polynomial interpolation method, a fifth-order polynomial equation for the .hivin.P-.ov...
This study postulates that, during granular collapses, there is a close relationship between two key quantities, velocity and pressure, and, therefore, the two should be measured simultaneously. In the present study's group, Liu et al. [18] previously carried out an experiment with Tekscan senso...
The following equation gives the relationship between the axial and lateral strains of confined concrete [2]: (5.60)εcεc0=0.85(1+8σlfc0)[{1+0.75(−εlεc0)}0.7−exp{−7(εlεc0)}] in which εl is taken as negative for tension and positive for compression. The partial deri...
