What types of materials are good conductors?
Water and metal are the two most well known conductors. They are conductors because they let electricity flow through them. Humans are also conductors because more than half of our body contains water. ...
How many gallons of water flows through half inch pipe?
It depends upon the velocity of flow and thus how much dynamic pressure you have. The length and type of pipe/hose will also contribute to the amount of friction, further reducing the velocity, pressure and available flow at the outlet. ...

Why as the water falls its speed increases and the area of cross section decreases?
It is explained by mass conservation, and water being an incompressible fluid. Imagine water going through a pipe with varying inside diameters Di's. Water will flow the fastest in the pipe section with the smallest diameter, and will flow the slowest in the widest section of the pipe. The product of the volumetric average velocity of the water flow v, times the cross section area A, is equal to the volumetric flow rate (vol/time) G. G = v∙A If you have a constant volumetric flow rate, if...
If you get 1.5 gallons of water per minute from a half-inch pipe what is the psi?
The PSI is whatever the incoming pressure is from the city water supply. The 1.5 gallons per minute is what the flow restrictor allows to flow from the fixture. ...

How does the rate of groundwater flow compare with that of moving ocean water or river currents?
Groundwater flow is very slow compared to currents in surface water, generally moving at less then one and one-half meters per day. ...

How many gallons of water flow over the niagara falls per second?
At an average rate of flow, about a half million gallons per second. That's 500,000 gallons. It may be as high as 750,000 gallons per second during high water flows. ...
What happens to nearly half the precipitation after it leaves the atmosphere?
After the water leaves the atmosphere half it falls to the earth and becomes groundwater, (water under the ground). And the other half is absorbed by plants. When the plants start to lose water from under their leaves through tiny holes called pores, this step is the next step in the water cycle. This step is called "Condensation". ...
How does a diode act as a half wave rectifier?
Diode only permits current flow in one direction. In AC the current waveform reverses for half the cycle. Since current won't flow for 1/2 the cycle you get half-wave rectification. ...
