# Calculation of pipe

Specify dimensions in millimetres

Internal diameter D1
External diameter D2
Pipe length L

## Calculation of pipe Specify dimensions in millimetres

D1 - pipe bore
D2 - external pipe diameter
L - Pipe length
The program will calculate the amount of water or another liquid in the pipes.
For calculating the heating system add to the volumes of output of the radiators and boiler.
This data is typically specified in the passport of the product.

As a result, the program calculates the total area of the surface of the pipe and the pipe size at 1 meter.
The surface area can be useful to calculate the amount of paint required.

For the calculation, specify the inner and outer pipe diameter and total length of the pipeline.
All dimensions are in millimeters.

Calculation of pipes are based on a formula V=π*R1*R1*L
Calculation of the surface area of the pipes are based on a formula P=2*π*R2*L
R1 - inner radius pipes
R2 - outer radius pipes
L - pipe length Service provided by www.zhitov.ru
