This is a model of pressure loss in a pipe. For the pipe flow, we assume that the pipe diameter D stays constant and that the pipe is straight. The pressure drop relates to the flow according to the equation below:



where

		:	Mass flow rate
		:	Fluid density
D		:	Inner pipe diameter
		:	Pressure difference between ports a and b
g		:	Standard acceleration of gravity on Earth
H		:	Height difference between ports a and b
		:	Kinematic viscosity of the fluid
L		:	Pipe length

Limitations

This class models steady, incompressible, laminar flow through a pipe.
