Explain bernoulli's principle?
In simple terms, if a fluid is flowing through a pipe, as the radius of the pipe decreases the speed of fluid flow must increase and visa-versa.
If you wish to double the speed of a fluid in a round pipe by what fraction must you reduce the radius of the pipe?
1/50
A piece of pipe is 303.4 inches long If five pieces each 41.3 inches long are cut from the pipe how many inches of pipe remain?
A piece of pipe is 303/4 inches long. If five pieces, each 41/3 inches long, are cut from the pipe, how many inches of pipe remain?
How much water does a pipe 6 inches in diameter times 500 feet long?
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.
Why do you measure the diameter of the pipe instead of the circumference of the pipe?
You could, but if you do, you will have to divide the circumference by π, and that's an irrational number. And, think of placing the pipe in a rectangular box with two sides the same length as the diameter of the pipe. It fits, and it makes the question much, much simpler. (Doesn't it? Sorry if my answer's too long.)
