Head loss and pressure loss
WebHead Loss – Pressure Loss. In the practical analysis of piping systems, the quantity of most importance is the pressure loss due to viscous effects along the length of the … WebMar 5, 2024 · The pressure difference ( ) between before and after the gate valve is measured directly using the pressure gauge. This can then be converted to an equivalent head loss by using the conversion ratio: 1 bar= 10.2 m water. The loss coefficient for the gate valve may then be calculated by using Equation (4).
