Summary

The basic idea presented here is to reduce the head of the main fan or pump only enough to balance the pressure drop along the trunk pipeline and to replenish the additional head with the variable speed fan and pump on each branch where the regulating valve and damper are otherwise installed. In this way no extra energy is wasted in flow-rate regulating. Gives examples of its feasibility.
