Blower power formula
WebCommon Blower Types Blowers can achieve much higher pressures than fans, as high as 1.20 kg/cm2. They are also used to produce negative pressures for industrial vacuum … WebSTEP 2 : calculate the air conveyor blower power. Outlet pressure = 0.35 bar g = 136325 Pa abs. Inlet pressure = 0 bar g = 101325 Pa abs. Power = 165 * 0.1338 * ln 136325/101325 = 6.55 kW. The pneumatic conveying blower needs to deliver 6.55 kW. Warning : this is not including efficiencies that need to considered on top of that.
