dp inWG = total pressure (in. W.G)
The actual power - brake horse power - a fan requires, because no fan is 100% efficient, can be expressed as
P BHP = q dp inWG / μ 6356 (2)
P BHP = Brake Horse Power (hp)
μ = fan efficiency
Systems for ventilation and air handling - air change rates, ducts and pressure drops, charts and diagrams and more.
The affinity laws can be used to calculate resulting volume capacity, head or power consumption when speed or wheel diameters are changed.
Fan classification established by AMCA.
Power consumption and typical efficiencies of fans
The temperature and density of the air influences on the volume flow, pressure head and power consumption in a fan.
