The new calculation results in 14.75 bar. This result
is still too high. In order to reach 12 bar, section 1 -
HDC must be changed.
The 9.25 bar of pressure loss achieved now are ide-
al. Thus, the determination of the nominal width for
this branch of the network is completed. The other
branches of the network are calculated the same
way.
The checking of the flow speed results in values that
range from 2...4 m/s (check against Table 2).
