The Hydraulic Gradient
In the pages on the flow of a fluid through pipes, it is seen that there is a loss of head. Whilst some of this is due to the effect…
Pipes – in Series or Parallel
Pressure loss in pipes connected in series or parallel Pipes in Series For pipes connected in series the pressure loss is the sum of the individual losses: dp = dp1 +…
Moody Diagram
The Moody diagram (also known as the Moody chart) is a graph in non-dimensional form that relates the Darcy friction factor, Reynolds number, and the relative roughness for fully developed flow in a circular pipe.…
Darcy Friction Factor
The Darcy Equation is a theoretical equation that predicts the frictional energy loss in a pipe based on the velocity of the fluid and the resistance due to friction. It…
DARCY’S EQUATION FOR LOSS OF HEAD DUE TO FRICTION IN PIPE
A pipe is a closed conduit through which the fluid flows under pressure.When the fluid flows through the piping system,some of the potential energy is lost due to friction. hƒ=4ƒLv²/2gD…
FLOW THROUGH CIRCULAR CONDUITS
PRE REQUEST DISCUSSION This page has an in dept dealing of laminar flow through pipes, boundary layer concept, hydraulic and energy gradient, friction factor, minor losses, and flow through pipes…
Reynolds Experiment
Reynolds number is the ratio of the inertial force of flowing fluid to the viscous force of the fluid. Inertial force of the fluid can be expressed as : Inertial…
Momentum Equation
DIFFERENCES BETWEEN SOLIDS AND FLUIDS The differences between the behaviors of solids and fluids under an applied force are as follows: i. For a solid, the strain is a function of…
Continuity Equation
When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow…
