Fluid mechanics, an ancient Greek concept, was first introduced by Archimedes around 250 BC. The first law of fluid mechanics, the conservation of mass, states that mass is conserved within a control volume for constant-density fluids. Isaac Newton, an ancient Greek, first described fluid viscosity in his 1687 Principia. The origin of fluid dynamics can be traced back to Leonardo da Vinci, who was educated at Plato's Academy. The Reynolds theory of fluid mechanics explains the relationship between mass and viscosity.
Open your very own WordPress Website (AD) The scope and purpose of Anderson’s manual are to give ordinary farmers enough practical understanding of electricity to design, install, and run their own small plants for lighting, heating, and motive power, using the modest water wheels or farm engines they already possess. Written in an accessible, story‑like style, it aims to demystify electrical technology and show that, under typical farm conditions, a private plant can be both technically feasible and economically comparable to buying a good workhorse. Scope Anderson deliberately narrows his scope to the small, self‑contained farm or cluster of neighboring farms that have access to a minor water‑power site or a gasoline engine, rather than to large commercial utilities or high‑voltage transmission systems. The book ranges from simple explanations of horsepower, head, and flow in a farm stream to the selection and coupling of water wheels and dynamos, sizing storage batteries, and laying...
