η D/A = (Concentration of Oxygen in inlet water(Ci)-Concentration of oxygen in outlet water (Co)) X 100 /(Concentration of Oxygen in inlet water(Ci))
Fans efficiency can be Mechanical efficiency or Static efficeincy.These are calculated based on static pressure & total pressure.
Static efficiency of the fan ηsfan= (Air flow in M3/sec X Static pressure in mmwc X 100) / (102 X Input power to fan shaft in KW)
Similarly mechanical efficiency can be calculated as
