There are two factors which determine the flow rate of water. Diameter and velocity. Resistance is not needed for determining the size of waterlines to their respective flow rates. Resistance is a component of velocity calculated for determining several aspects such as pump hp, and loss of velocity over a distance. The formula without the resistance component is: Q=Av where: Q=Flow Rate A=Inside pipe area v=velocity Calculate: Q= (3.14XR squared)v lets assume a velocity of 10 inches per minute For 1/2 inch pipe: Q = (3.14 X 1/4" X 1/4")X10 inches per minute Q = 1.96 Cubic inches per minute For 3/4 inch pipe: Q= (3.14 X 3/8" 3/8") X10 inches per minute Q = 4.41 Cubic inches per minute So one 3/4 inch pipe will carry roughly 12% more water than two 1/2 inch pieces.

Thermal expansion.An exhaust pipe gets up to 600 degrees or more. The coefficient of expansion of steel is 8 millionths of an inch per inch per degree. a 12 foot exhaust increasing (and decreasing) in temperature by 500 degrees will expand overall a little more than 1/2 inch. If the pipe were mounted solidly the mounting bracket would eventually break, or the pipe would break, from the strain put on it by the expansion.
The gauge of the pipe is the wall thickness. It is easier to say Schedule 40 pipe than .180 inch wall thickness. This is the SCH 40 wall thickness for a standard 12" pipe and the actual gauge thickness will vary based on pipe size and material. The larger the Schedule number, the thicker the pipe wall thickness. Pipe Schedule is also expressed in Std., X-Stg., and XX-Stg. since some thicknesses are more common than others.
A slope of 1/4" in 12' is 0.0017 - inadequate for cleansing; it should be at least 0.0084 to produce a reasonable flow velocity of 2 ft/sec. The metric slope I was informed is 18mm in 1000mm Most codes require a 1/4" slope for each 12" of run.
The maximum flow rate for a 1 inch diameter pipe is typically around 8-12 gallons per minute. To calculate the maximum volume, you would need to multiply the flow rate by the amount of time the water is flowing.
That depends entirely on the viscosity of the liquid in the pipe ! Water would flow faster than oil !
The volume of a 12 inch x 12 inch pipe is: 1,360 cubic inches
The circumference of 12-inch pipe is: 37.7 inches. (C = d x Pi)Since 12 inch pipe is a nominal size and its outside diameter is 12.75 inches, the circumference of 12 inch pipe actually is : 40.035 inches
To calculate the flow of water in a pipe, you would need to know the diameter of the pipe, the pressure (40 psi), and the fluid properties. The flow rate can be determined using the Darcy-Weisbach equation, taking into account the pipe diameter, pressure, and fluid characteristics. Without more information, it is not possible to determine the flow rate accurately.
you cannot have 12 inches of a 6 inch pie silly!!!(think about it)
You multiply the radius of the circle 0.5 (radius of a 1 inch pipe) by 3.14(pi) by the height of the pipe 12 inches which gives you 18.84ozs.
To find the volume of a pipe, you can use the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height of the cylinder. For a 2-inch diameter pipe, the radius is 1 inch. Thus, the volume of 12 inches of 2-inch pipe would be π * 1^2 * 12 = 12π cubic inches.
12 threads per inch. right handed
A 12 inch diameter round pipe will hold 4.89 UK gallons or 5.88 US gallons per foot.
The meaning of dia inch is the number of weld joints multiplied by the dia of a given pipe size, since the weld joints is on the 6" pipe, the calculations should be 1 weld x 6" = 6 dia inch.
With large diameters like that you will most probably need to insert a weld-on 12 inch - 10 inch reducer at the point where the reduction is required. The pipe and reducer perimeter edges should be bevelled, say 45 degrees, for good weld penetration especially if the pipe conveys fluid under pressure.
