HEAD LOSS CALCULATION IN VENTILATION NETWORKS USING

The equal friction method is the more common one and, as the name implies, results in a system in which the duct static pressure reduces at a constant rate down the length of the duct. So for example if a duct is 30m long and is designed for a friction rate of 0.1Pa/m, the static pressure at the end of the duct will be 30Pa lower than at the beginning. This is for a simple straight duct and

Fig. 5 shows that the design under DPM produces the smallest total surface area, meaning its initial cost would be the smallest in comparison with other methods, followed by equal friction method. Static regain method results in the highest initial cost, because it has bigger duct size and requires lower fan pressure.
