The mass flow rate at ports A and B are equal in magnitude and opposite in sign. This behavior can change if you enable fluid dynamic compressibility. Because compressible fluid can accumulate in the pipe, the mass balance equation has additional terms, where: V is the pipe fluid volume. ρ...
fluid flow rates. In these situations, the Darcy Friction Factor formula can be used to predict frictional pressure loss. In this equation, Delta P is the pressure loss over a length L for a channel with a circular cross-section and an internal diameter D, row is the fluid density, and ...
A higher pressure drop acting on a pipe creates a higher flow rate. A wider pipe also produces a higher volumetric flow, and a shorter pipe lets a similar pressure drop provide a greater force. The final factor controlling a pipe's viscosity is the fluid's viscosity. This factor measures ...
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 ...
m.s. velocity and the turbulent kinetic energy is: (8)k=u'2/2 This relationship is correct even when the turbulence is not isotropic. Substituting Equation (8) in Equation (7) leads to: (9)C′P2=8k02/U¯04+8C¯P2(U¯02k0−U¯12k1)/(U¯02+2k0−2k1)2 This reduces...
The Pipe Flow Wizard software helps engineers worldwide with their pipe flow calculations, making it easy to calculate pressure loss, calculate flow rate, size a pipe diameter and calculate pipe length. It allows them to perform "What If?" calculations on both liquids and gases flowing in a...

This effectively gives energy released or gross MEP (gross work over the compression and expansion cycle, GMEP). Net IMEP for a single cylinder is derived by subtraction in the following equation: (16.8)IMEP(Net)=(area of high pressure loop)−(area of low pressure loop)Vs Integration of ...
