[ Liquid Pump Suction ] ------------> 0.5 to 1.5 m/s [ Liquid Pump Discharge ] -----------> 1.5 to 3.0 m/s [ Saturated Steam Lines ] ----------> 20 to 30 m/s [ Superheated Steam / Gases ] ------> 30 to 60 m/s Explicit Sizing Formula

Step 3: Account for Fitting Losses (Equivalent Length Method)

Re=ρvDμcap R e equals the fraction with numerator rho v cap D and denominator mu end-fraction : Fluid density ( : Fluid velocity ( : Inside diameter of the pipe ( : Dynamic viscosity ( Laminar Flow ( [ Liquid Pump Suction ] ------------> 0

tnominal=t+c1−Tolt sub n o m i n a l end-sub equals the fraction with numerator t plus c and denominator 1 minus cap T o l end-fraction

Process piping hydraulics is the study of the behavior of fluids flowing through pipes. The primary goal is to determine the pressure drop (head loss) required to transport a fluid from one point to another at a specified flow rate. This equation is based on the conservation of

: Darcy friction factor (obtained from the Moody Diagram or the Colebrook-White equation) : Pipe length ( : Acceleration due to gravity (

Verify the Reynolds number to confirm the fluid is within predictable turbulent limits. This creates a shock wave that travels through

This equation is based on the conservation of mass, which for incompressible fluids, states that the mass flow rate is constant throughout the system. It explains why fluid velocity increases when it flows from a larger pipe into a smaller one.

= Mill manufacturing tolerance (typically 12.5% for seamless steel pipes, or expressed as a decimal: 0.125) The resulting tnominalt sub n o m i n a l end-sub

Sudden valve closures or pump trips cause rapid momentum changes. This creates a shock wave that travels through the liquid column at the speed of sound:
