1 Pressure and Flow rate Pressure Definition Absolute Pressure: Absolute pressure is the force per unit area applied to anything, whether that anything is a solid, liquid or gas.
Figure 1: Pipe friction loss. For horizontal pipe, with constant diameter this loss may be measured by height of the pressure drop: ∆p ρg =h We must remember that equation (4) is valid only for horizontal pipes.
2 values recommended for commercial pipes given in textbook on Fluid Mechanics by F.M. a White is provided at the end of these notes. Colebrook Equation
Pressure drop in pipes.... PRESSURE DROP CALCULATIONS Pressure drop or head loss, occurs in all piping systems because of elevation changes, turbulence caused
Hydrotest Pressure What is the definition of Hydrotest pressure is often a question many engineers have in their mind. Most piping engineers consider Hydrotest pressure as 1.5 times the design

INSTALLATION WATTS pressure reducing valves may be installed in all positions. They are generally installed directly after the water meter, and thus protect
