If you are looking for a calculator to perform pipe sizing and pressure drop calculations please jump to the AioFlo page. The sizing of pipes for optimum economy requires that engineers be able to accurately calculate the flow rates and pressure drops in those pipes. The purpose of this document is to discuss the various methods available to support these calculations. The focus will be on the methods for calculating the minor losses in pipe sizing and to consider in particular the following aspects:. Over the years excellent progress has been made in developing methods for determining the pressure drop when fluids flow through straight pipes.

The simplest way to convey a fluid, in a contained system from Point A to Point B, is by means of a conduit or pipe Fig. The minimum basic parameters that are required to design the piping system include, but are not limited to, the following.
The pressure drop calculations are based on the D'Arcy-Weisbach Equation with the following parameters:. A diagram presentation of the tables above can be found in " Steel Pipe Schedule 40 - Friction loss and Velocity Diagram ".

Friction loss is a significant economic concern wherever fluids are made to flow, whether entirely enclosed in a pipe or duct, or with a surface open to the air. In long pipes, the loss in pressure assuming the pipe is level is proportional to the length of pipe involved. When the pressure is expressed in terms of the equivalent height of a column of that fluid, as is common with water, the friction loss is expressed as S , the "head loss" per length of pipe, a dimensionless quantity also known as the hydraulic slope. Friction loss, which is due to the shear stress between the pipe surface and the fluid flowing within, depends on the conditions of flow and the physical properties of the system. These conditions can be encapsulated into a dimensionless number Re, known as the Reynolds number.
By: Jorge Solorio on August 28th, In our previous post , we discuss the various formulas used to determine flow rate, flow velocity and pressure loss, as well as the factors that piping material selection plays in optimizing fluid handling. Read the full post, here.
Investigation of pressure drop in horizontal pipes with. The above table indicates, Chart B should be used Step 1. Pressure drop is defined as the difference in total pressure between two points of a fluid carrying network. A pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through the tube.
To calculate the pressure loss in a pipe it is necessary to compute a pressure drop, usually in fluid head, for each of the items that cause a change in pressure.
