# Calculations

#### Hydraulic performance of non pressure systems

Flow rate and speed calculations for sewer, rainwater and drainage systems (Colebrook White)

Calculate#### Culvert hydraulic calculations

Throughput and flow rate calculations for GIGAPIPE culvert systems. The parameters of the culvert are determined by the Manning-Strikler formula, which includes losses from contact with the culvert walls.

Calculate#### Cable protection pipe construction

Permissible construction depths and deformation calculations

Calculate#### Linear expansion/reduction

Calculate linear expansion or reduction of the PE100 or PE100-RC material pipeline as a result of temperature change.

Calculate#### Horizontal directional drilling calculations

Calculation of pipe pulling force and length according to GW 321

Calculate#### Calculations for energy-absorbing chambers

How to select energy-absorbing chambers connection sizes and determine the throughput.
