surface area divided by volume
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
Surface area of the pipe: diameter*pi*length but make sure that the diameter and length are both in meters or inches.
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.
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.

to calculate the area of the front surface of a box you should
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
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 divided by volume
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
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
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.
Surface area of the pipe: diameter*pi*length but make sure that the diameter and length are both in meters or inches.
To calculate square footage of a pipe you need to use the area formula of a circle, a=1/2bh. then find the circumference of the entire pipe.
