Pressure loss in pipe, which are associated with frictional energy loss per length of pipe depends on the flow velocity, pipe length, pipe diameter, and a friction factor based on the roughness of the pipe, and whether the flow is laminar or turbulent (i.e. the Reynolds number of the flow). Although the pressure loss represents a loss of energy, it does not represent a loss of total energy of the fluid. What is the equation for pressure loss?What is the equation for pressure loss?By observation, the friction loss in pipe is roughly proportional to the square of the flow rate in most engineering flows (fully developed, turbulent pipe flow). The most common equation used to calculate pressure loss in pipe, tube or duct is the DarcyWeisbach equation .What is Pressure Loss in Pipe - Friction Loss in Pipe - Definition

PEX tubing technical specifications and general pe pipe pressure loss introductions

Since PEX is a flexible pipe, it will expand somewhat (especially PEX-a) during the initial pressurizing of the system, causing a drop in pressure reading. Some manufacturers recommend "conditioning" of the system, or allowing the PEX system to stay pressurized for about 30 minutes prior to taking a reading.Pipe Newsletter Industry News Insight from WolseleyPlastic Pipe and Fittings Pressure Plastic Pipes and Fittings PE Pipe and Fittings Pipe Support Systems Metering Drainage View All Drainage Waste Pipe and Fittings pe pipe pressure loss introductions Introduction from Chris Neal, Regional Operations Director.
