Depending on the length of the pipe, it could range from nearly none to billions of gallons!
A pipe does no water. Te capacity of the pipe with the given dimensions is approximately 98.2 US gallons. Whether or not the pipe holds any water is impossible to say.
Depends on the diameter of the pipe and the speed at which the water travels through it.
There is no obvious reason why there should be any water in the pipe. Furthermore, there are no units associated with the width of the pipe, so its volume cannot be calculated.
A gallon is a measure of volume and that requires more than one dimension.
One possibility is the word pipe. For example, water flows threw pipes.
One word; 'windpipe'.
We need to know more info. such as, is the pipe cooled, air or ground temp. around the pipe. what temp is the water.
leaking
Insufficient information, one needs to know the pressure of the water entering the pipe, the relative heights of both ends the pipe, the pressure of the water at the discharge of the pipe, the geometry of the pipe including the number and types of turns, and the pipe material or internal friction coefficient. Then you can calculate the flow.
There need not be any water at all in the pipe. The capacity of the pipe is approx 3.4 Imperial gallons.
The capacity of one foot of a pipe with an inner diameter of 20 inches is approx 1.36 US gallons. The maximum amount of water is, therefore, 1.36 gallons, but there need not be any water in the pipe.
Hot water pipe rust first as compared to the cold water pipe for the same chemical composition of the water.
Yes, as long as the water coming out of the pipe has a greater pressure than the water that is covering the pipe. If it is the other way around, the water covering the pipe will actually flow into the pipe. Think about it. It just makes sense.
One has water in it or wet .one is emptyfull of air snd has flapervalve
Supply coming from water source is a water service line.
The flux of the water out of the pipe was very high.
