Projects From 1900 That Will Help You In The Next Crisis

"The USA in 1900 wasn’t a backwards country. In fact, it had one of the most advanced economies in the world. The Industrial Revolution might have started in Britain, but by the Great Exhibition in 1851 the British were amazed at the variety and quality of things being made in the USA. Even so, if people could do something themselves they generally did. They didn’t hesitate to take on big jobs, either – many turn of the century DIY projects were a lot more ambitious than putting up some new shelves in the den. In this book we’ll look at some typical projects our not so distant ancestors were familiar with, and which can still improve our lives today."

Hydraulic head (Hydrology 💧)

Hydraulic head or piezometric head is a measurement related to liquid pressure and the liquid elevation above a vertical datum. It is usually measured as an equivalent liquid surface elevation, expressed in units of length, at the entrance of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well, and given infor...

Hydraulic head (Hydrology 💧)

Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well, and given information of the piezometer's elevation...

Drawdown (hydrology) (Hydrology 💧)

In hydrology, there are two similar but distinct definitions in use for the word drawdown: In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. In surface water hydrology and civil engineering, drawdown refers...
