A "4-inch pipe" means it has a diameter of 4 inches, which makes the radius 2 inches.
Did you ever see the formula pi*r^2 for area of circle?
The answer is 4pi where pi=3.1416

8 inch schedule 40 pipe has a cross sectional area of 0.0583 square feet
Method to find area of a circle is: The area of a circle is its radius squared times pi. Assuming the pipe has a diameter of 4cm: radius = 2 cm Circumference = 12.5664 cm Area = 12.5664 cm2
The answer depends on the cross section of the pipe and its length.

Cross-sectional area of pipe is π(1.5)² = 7.07 cm² that means the flow is 10 cm/s x 7.07 cm² = 70.7 cm³/s 70.7 cm³/s x 60 sec = 4240 cm³ or 4.24 Liter
8 inch schedule 40 pipe has a cross sectional area of 0.0583 square feet
It depends on what you mean by a 30 pipe. Is 30 the cross sectional area - in which case, what is the length of the pipe? Is 30 the length - in which case, what is the cross-sectional area?
It's not likely that any property of fluids correlates in any way with any Vatican situation. If a pipe of X cross sectional area is connected so a fluid flows at a specific velocity, and then a pipe of 2X cross sectional area is connected to the pipe of X cross sectional area, the velocity of fluid flowing in the 2X pipe will be less than what is flowing in the X pipe. In this case, what you're saying is true.
It depends on the cross sectional area of the pipe.
To start, we will find the cross sectional area of the pipes. Pipe with radius of 2 inches Cross sectional area = PI x radius2 = 12.56 inches2 Pipe with radius of 3 inches Cross sectional area = PI x radius2 = 28.26 inches2 Pipe with radius of 5 inches Cross sectional area = PI x radius2 = 78.5 inches2 As the cross sectional area of the pipe with a radius of 5 inches (78.5 inches2) is greater than the sum of the cross sectional areas of the pipes with radii of 2 inches and 3 inches (40.82 inches2), it can be concluded that the pipe with a radius of 5 inches will be able to carry the most water. (Assuming that all three pipes are the same length).
It all depends upon the shape of the container that it is in. For example, if the water weighs 8 lbs per gallon, then the water at the bottom of a container that is a vertical pipe with cross sectional area of 1 square inch will exert a pressure of 8 psi. However, if the water is in a vertical pipe with cross sectional area of 8 square inches, then the pressure at the bottom of the pipe will be only 1 psi.
It's not supposed to change. If the cross-sectional area does change through a bend, then the pipe is said to be "kinked". The bend is regarded as poorly done, and if the kink is deep enough, the section of pipe including the bend may have to be replaced.

The pipe's volume is the product of its cross-sectional area and its length. The area of a circle is pi*(radius)^2, so in this case pi*9sq.in. or about 28.3 square inches. Multiply this area by the length of pipe you are using to obtain a volume. A 10 foot length of 6 inch pipe will have 3393 cubic inches of volume or 1.96 cubic feet, or 14.7 US Gallons.
Method to find area of a circle is: The area of a circle is its radius squared times pi. Assuming the pipe has a diameter of 4cm: radius = 2 cm Circumference = 12.5664 cm Area = 12.5664 cm2
The volume of the interior of a pipe (or any circular cylinder) is the cross-sectional area multiplied by the length (volume = pi x radius x radius x length).
