Jadual di bawah adalah kesimpulan secara menyeluruh perbandingan HDPE pipe dan GI pipe.

1. HDPE (High-density polyethylene)- High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylenethermoplastic made from petroleum. It is sometimes called "alkathene" or "polythene" when used for pipes.
2. GI (Galvanized Iron)- These are carbon steel pipes, which have a zinc coating done using Galvanization process. Galvanizing may be done using two methods, Hot-dip galvanization and Electrogalvanization.

POWER FACTOR CORRECTION

Q = P x (tan Ø°1 – tan Ø°2)

Where,

Q is the reactive power required capacitor in VAR unit

P is the real power in Watt unit

cos Ø1 power factor before fixed

cos Ø2 power factor after fixed
