The U.S. Geological Survey (USGS) and the Food and Agriculture Organization of the United Nations (FAO) have teamed up to create a water-cycle diagram for kids and elementary and middle schools. The diagram is currently available as a PDF in two sizes: Tabloid size (11x17 inches) - 2 Mb; Poster size (33x24 inches) - 2 Mb; JPG image formats for ...
Definitions, online calculator and figures and tables with water properties like density, specific weight and thermal expansion coefficient of liquid water at temperatures ranging 0 to 360°C (32 to 680°F).
This simulation shows a pressure-enthalpy (P-H) diagram for water. Check and uncheck the boxes to add or remove a property from the diagram. You can show lines of constant vapor quality q (blue), temperature T (red), density ρ (gold) and entropy S (purple).
Our Water Cycle lesson plan teaches students about the different steps of the continuous process that Earth's water follows. Free PDF!
Pressure-Enthalpy Diagram for Water - Ohio University
There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. 1) Evaporation. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air.
The water cycle describes where water is on Earth and how it moves. Water is stored in the atmosphere, on land, and below the ground. It can be a liquid, a solid, or a gas. Liquid water can be fresh or saline (salty). Water moves between the places it is stored. Water moves at large scales through watersheds, the
