Pressure lose and pipe connection

Air pressure lose = Pa / m ; Telescopic pipe 8 Pa / m ; PC 5 Pa / m

The following principles should be followed when selecting and installing pipes

A , Because the length of the pipeline is not proportional to the pressure loss along the way ,

the length of the pipe-line should be minimized (generally not more than 4 m ) .

B , Since the number of bends of the pipe is proportional to the local pressure loss ,

the number of corners should be reduced as much as possible .

C .Since the pressure loss of the circular cross-section is smaller than other shapes ,

circular pipes should be used as much as possible .

Pipeline installation must not have the following conditions
