Impeller peripheral speed
WitrynaGiven the high peripheral speeds of flywheels, the aerodynamic friction loss would be excessive unless the pressure inside the casing is reduced. Losses occur due to the … WitrynaPeripheral Speed. Consequently, the peripheral speed drops when entering the contact area, which suggests a negative shear stress at that point (as the rubber is being …
