90 PSI is a bit high....you can check water flow (gallons per minute) by filling up a 5 gal bucket at full open and time it.
Channel flow is how much water flows through a channel.
question cannot be answered because it depends on the water pressure
That depends on the pressure behind the flow, and on the length of time the flow is allowed to continue.
10ppm of copper what mass of this rock must water flow. 10/10^6=2000/x=2E8 kg
about 16,000 tons flow through space and go on the edge of saturn atmmsphere
300 gallons per minute
Yes, water can pass easily through gravel because of the large pore spaces between the gravel particles. This allows water to flow through the gravel layer without much resistance.
Have to much water flow
300mm is a very low head, you can't expect much flow through that pipe, but you can work it out from the mechanical energy balance equation.
Depends on what's flowing (gas or water or something else) and under how much pressure.
Sprinkler valves work by opening and closing to regulate the flow of water in a sprinkler system. When the valve is open, water is allowed to flow through the pipes and out of the sprinkler heads, watering the designated area. When the valve is closed, water flow is stopped, preventing water from reaching the sprinkler heads. This control is typically achieved through the use of a solenoid that is activated by an electric signal, allowing for precise control over when and how much water is distributed.
Not much of it. Much of the earth's waste is dumped into large holes and left to rote. This left for water to flow through it, and join up with water systems underground, which eventually join up large overland water systems as infected water.
