A book about basic water machines/properties/flow ??? Hi I'm interested in how different very basic water concepts/properties work such as a waterpump, pressure, hydroponic systems for plants etc. ( i need some intuition) and I'm therefore looking for a book that teaches basic properties of fluid, pressure in a easy to understand (not any heavy equations and fluid mechanics for ingeneers) and way with pictures perhaps practical demonstrations. I'm interested in exploring some of the properties of water, so i can use it in biology to biold small basic systems such as a water pump. I've found one book so far that might be what i'm looking for but i'm not sure if it has good pictures and explanations . https://www.amazon.com/H2oh-Classro...=sr_1_1?s=books&ie=UTF8&qid=1372540283&sr=1-1 Any suggestion?
