Which is pipe strength expressed in?

Pipe strength is primarily expressed in terms of tensile and flexural strength. Tensile strength refers to the maximum amount of tensile (pulling) stress that a material can withstand before failure, while flexural strength indicates the material's ability to resist deformation under load. These measures are crucial in assessing how well a pipe will perform under various stresses during its use in water distribution systems.

Understanding tensile and flexural strength is important for engineers and technicians when selecting materials for pipes, as it ensures that the pipes can handle not only the internal pressure of the fluids they transport but also external forces such as soil load and environmental conditions over time. Accurate assessments of these strengths ensure that the pipes will not fail prematurely, thereby promoting safety and reliability in water delivery systems.

Other options, like hydrostatic potential, psi, or baud units, do not directly define the mechanical strength of pipes in a relevant context for water distribution.
