What additional factor affects the pressure requirements of a piping system?

The pressure requirements of a piping system can be significantly influenced by the temperature of the fluid being transported. As temperature increases, the behavior of the fluid changes, including its viscosity and density, which can affect the pressure within the system. A higher temperature can lead to increased pressure due to thermal expansion of the fluid. Additionally, some materials used in piping may have temperature thresholds beyond which they may not safely contain the fluid at certain pressures, necessitating adjustments to pressure requirements to ensure safety and compliance with standards.

Piping systems must be designed to accommodate not only the pressures generated by the pump or other forces but also the variations that can arise from changes in temperature. Thus, understanding and accounting for the temperature of the transported fluid is vital for maintaining the integrity and safety of the piping system. This is why temperature is a key factor when considering pressure requirements.
