Does water flow from low pressure region to high pressure region?
Asked in Science, Meteorology and Weather, Clouds
How do fluids flow using the terms of low and high pressure?
Does a water meter only measure the time that the water is flowing past it assuming that the water is always flowing at a constant pressure?
No. Most water meters are of the positive displacement type. They meter actual volume, and are pressure independent. Also note that water flow and pressure are not the same thing. You can have high flow with low pressure, and also low flow with high pressure, depending on the size of the pipe and/or openings (such as valves) and the pressure.
Why do you measure electricity in volts and amps?
What is meant by the terms current and volts?
Volts is the potential energy of the electricity and current is the amount of flow. If we compare electricity to water. Volts would be the water pressure and current is the hose size. Squirt gun has high pressure but low flow. A fire hose has high pressure and high flow. The sink drain has low pressure but high flow. All have specific use. Static charge, high voltage low current. Car starter low voltage high current. Electric car motor high voltage and high current
