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.

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.
