To calculate the surface area of a pipe fitting, you need to use the formula 3.14 x L x D. The L stands for the length of the pipe and the D is the diameter of the pipe.
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
Inside area: pi1.51 square inches
The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on. Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off.
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.

If your elbow is a short radius it is 1 times your nominal pipe diameter. If it is a long radius it is 1 1/2 times your nominal pipe diameter.show me the exact pattern of long radius
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.
Surface area of the pipe: diameter*pi*length but make sure that the diameter and length are both in meters or inches.
No, it is a pipe! (with apologies to Magritte!)
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.
The easiest way is to find the centerline length and multiply that by the linear weight of the pipe size being used. Alternatively, this formula should give the weight of an elbow in pounds: w=0.071*pi^2*R*(ro^2-ri^2) Where: w= weight of elbow (lb) R=curve radius of elbow (in) ro=outside radius of pipe (in) ri=inside radius of pipe (in)
