Hydraulic calculation of the pipeline online

Hydraulic calculation of pipes is performed to select the optimal diameter at which the pressure loss (water friction against the pipe walls) will be optimal and cost-effective. Losses per 1 meter of pipes, depending on the material, are accepted 80 - 250 Pa / m or 8 - 25 mm of water column.The speed of water in pipes, depending on the diameter, must be in a certain range. The maximum water velocity for heating systems is1,5 m/s. Recommended limits for water velocity in pipelines for internal diameter:15 mm – 0,3 m/s, 20 mm – 0,65 m/s, 25 mm – 0,8 m/s, 32 mm – 1 m/s everyone else no more than 1,5 m/s. In fire-fighting pipelines, the speed of water movement is allowed up to 5 m/s.

Do you want to order a hydraulic calculation of a home heating system, plumbing, sewerage, heating networks, gas supply ?
To do this, our specialists need the following technical data: for house heating - floor drawings with the arrangement of heating devices, for heating networks and water supply - plans with heat sources / wells on a scale, for sewerage - topographic and geodetic survey with sources drainage. After receiving these data, we can calculate the cost of the hydraulic calculation. Assignments are accepted by e-mail project(@)mathcentre.com.ua (pay attention (@) - this is protection against bots and spam, of course without brackets) marked "hydraulic calculation of pipelines". Payment is accepted by any means known to you. Lead time 3 business days.

For planning external engineering networks of water supply, sewerage, rain sewerage and heating networks of cities and towns - TEIs (Technical - economic indicators).
