Probably one of the most critical areas of plumbing design involves WS calculations, be it a small house or a huge commercial building. You should determine how much water the system will actually require. If the water demand in a plumbing system is calculated well, it will function smoothly. Otherwise, problems may pop up anytime with low pressure, flow variations, or noise in the pipes.

Below is a simple guide that will explain WS calculations in a way even a complete beginner can understand.
