Lesson Overview
Force and pressure are core scientific principles that determine how water is stored, balanced, and distributed through plumbing systems. Understanding force, head of water, and pressure conversions is essential for safe system design and installation.
Learning Objectives
Calculate force in newtons using mass and the acceleration due to gravity.
Determine pressure in pascals and convert accurately between metres head, bar, and kilopascals.
Distinguish between static, dynamic, and atmospheric pressures in plumbing systems.
