Water pressure is the force exerted by water in a system, typically measured in units like pounds per square inch (psi) or pascals (Pa). It is influenced by factors such as the height of the water source, the amount of water flowing, and the size of the pipes. Higher water levels create greater pressure due to the weight of the water above. In everyday life, water pressure affects how water flows from taps and showers. For example, a water tower uses gravity to maintain consistent pressure, ensuring that homes receive adequate water supply. Low water pressure can lead to weak streams, while high pressure can cause leaks or damage to plumbing systems.
