m--exponent of velocity or flow rate for a particular formula of head loss (m = 1 for laminar flow and m = 2 for full turbulent flow in the

Darcy-Weisbach equation); and,

The pump head calculations, including piping, all fittings, valves, and devices, are achieved by using the

Darcy-Weisbach equation with given flow parameters.

The pipeline model is a closed loop comprised of two volumes of half the total pipeline volume connected to the compressor and a flow resistance [DELTA]p characterized by the

Darcy-Weisbach equation:

The most complicate is to evaluate friction coefficient [[xi].sub.2] which could be calculated with

Darcy-Weisbach equation [13]:

Pressure drop caused by the friction of a fluid flowing in a pipe may be described by the

Darcy-Weisbach equation (1):

The

Darcy-Weisbach equation for pressure drop in a pipe is:

The inherent resistance of the test rig, which corresponded well to the

Darcy-Weisbach Equation for flow in a smooth tube, was subtracted from the measured data.

A new explicit equation for the friction coefficient in the

Darcy-Weisbach equation. In: Proceedings of the Tenth Conference on Protection and Restoration of the Environment, v.

(A flow of 6 cfm [2.8 L/s] was used because the graphic scales best with such a value.) The actual pressure drop is calculated in Column H using the

Darcy-Weisbach equation, converted to inches of water.

The resistance corresponded well to the

Darcy-Weisbach equation for the whole flow range examined, and the additional resistance was subtracted from the total measured media resistance.

Using the f calculated by the Blasius equation, associated with the

Darcy-Weisbach equation, this exponent is equal to 1.75.

The pressure drop can be estimated using the

Darcy-Weisbach equation for turbulent flow in pipes.
