Fluid Mechanics - Fundamentals - Pressure Drop in a Pipeline

This documentation provides the basic knowledge to estimate the pressure drop across a pipeline. Firstly, we delve into the basic equations of ideal gas law and combined gas law. From these basic equations we derive the local and average gas density as well as the local and average gas velocity, which we use them to calculate the gas pressure drop in a pipeline. The pressure drop is itself a function of friction factor λ, Length of the pipe L, internal diameter of the pipe D, gas density and gas velocity. This documentation will demonstrate the two methods to estimate the gas pressure drop across a pipeline by using an example. The two methods yield the same result in terms of pressure drop. These both methods can be applied for design of a pneumatic conveying system. Quick Overview - Pneumatic Conveying :    • Overview of Pneumatic Conveying  .
