Note! - be aware that evaporation pressure - and possible cavitation - increases dramatically with water temperature.
Cavitation can be avoided by locating components to the coldest part of systems. Example - it is common to locate pumps and modulating valves in heating systems in the "cold" return lines before heaters and heat-exchangers.
The study of fluids - liquids and gases. Involving velocity, pressure, density and temperature as functions of space and time.
Piping systems and pumps - centrifugal pumps, displacement pumps - cavitation, viscosity, head and pressure, power consumption and more.
ABMA recommended feed water chemistry limits for steam boilers.
