(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter
Calculate as you would the surface of a cylinder who's height is the length of the central line of the pipe bend.(2*π*r*h)where:r is the (external) radius of the pipeπ is the constant 3.14159... andh is the length of the cylinder or the center-line of the pipe bend
measure the length of the fitting first. Then insert pipe into fitting and mark a line on pipe. measure that bit of pipe. deduct off the length of fitting and half it to give you your x dimension
Inside area: pi1.51 square inches
For a pipe of uniform radius and thickness, I believe the total surface area would be the Outside surface + Inside surface+ 2 times the surface of the ends. The inside radius(rinner), pipe thickness (t), and pipe length (L) are given.So you only need to find the outside radius (Rout) and then all areas can be calculated.The outside radius should be Rout=rinner +t. And note the perimeter of a circle is 2*pi*Radius and area of an annular region (in this case the ends of the pipe) is A= pi*(Rout2 - rinner2)For the outer pipe surface: Aout=2*pi*(Rout)*LFor the inner pipe surface: Ainner=2*pi*(rinner)*LFor each pipe end: Aend= pi*(Rout2 - rinner2)So the total surface area of the pipe would be: Aout+ Ainner+2* AendOr: Atotal =2*pi*(Rout)*L+2*pi*(rinner)*L+ 2*pi*(Rout2-rinner2)= pi*[ 2*L*(Rout + rinner)]+(Rout2 - rinner2)= 2*pi*[ L*( rinner +t + rinner)]+(( rinner +t )2 - rinner2)]=2*pi*(t+L)(t+2*rinner)Hopefully that is correct and helps.

The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.

Start with the maximum flow speed (metres per second) for your liquid, then mutiply by the area of the pipe in square metres, the result is maximum volume flow rate in cubic metres per second.

Well, calculating the square footage of a pipe is a lot like painting a happy little tree. First, you measure the circumference of the pipe using a tape measure. Then, you use a simple formula to find the area of the pipe's cross-section: Area = πr^2, where r is the radius of the pipe. Just remember, there are no mistakes, only happy accidents in math and painting!
Surface area of the pipe: diameter*pi*length but make sure that the diameter and length are both in meters or inches.
The fitting allowance is the difference: (pipe end to fitting center measurement) minus (pipe end to end measurement). It is the amount of length the fitting adds to the end of the pipe (to get the center of the turn).
To calculate how much paint needed for pipe painting, the pipe must first be measure for area. After the area is calculated, the amount of paint needed can easily be found out by figuring out how much area each can covers.
2*pi*r*L where r is (outer) radius of the pipe (in case of the outer surface) nd L is the length of the pipe.
