I am on a plumbing training course and just when I think I understand how to calculate water pressure, intensity of pressure and total pressure in Newtons and Pascals then someone tells me something different and I'm back to square one. The formulae in the books look simple enough until I try them on an actual example. Can someone explain in SIMPLE terms what the formulae are for these 3 and give me an example. Please make your answer suitable for an IDIOT as I feel like one right now.
The formula looks like Newtons should be multiplied by m2 but then it's written N/m2 which looks like it should be divided not multiplied. Can anyone make this clear, please??
