Water flow regards the quantity of this fluid medium per a unit of time. In SI units it would be liters per second (lps), and in American it is commonly measured in gallons per minute (gpm).
Can't be applied in the region close to the boundry.Can't be applied to sharply converging flow.Can't describe wakes.
That depends on what information is provided. If you don't have any information, you may actually need to measure the speed of the water; or you may want to measure the flow (for example, in liters per second), and the pipe diameter, and then calculate the speed from that.
a natural flow of water from underground
This is the ratio volume/time.
1- Used in fluid mechanics laboratories. 2- to calculate discharge rate of water. 3- For giving continuous flow.
(to check the flow rate of water ... calculate the pressure drop
Before you can calculate the flow, you must also have the pipe size and its coefficient of friction.
The question is incomplete, therefore this answer is..............
Most plumbing or pipefitting suppliers have charts that show what size pipes you need to provide the proper flow rates at various pressures.

I want to know based on flow and pressure how to calculate diameter of the pipe
water cannot flow uphill
I do this often, the simplest, fastest way is to let it fill a 5 or 10 gallon bucket and time it with a stopwatch.
the water aways flow because it does
