Abstract

Calculated drag force on housing wall = 5.39 x 10-3 N Calculated drag force on housing endface wall = 3.88 x 10-4 N Form drag calculation for valve stop: Valve stop width: 10 x 10-3 m Valve stop length: 22.53 x 10-3 m Calculated valve stop area = 2.25 x 10-4 m 2 Radial displacement of valve stop from cylinder centre: 59.5 x 10-3 m Calculated radial speed at 1000 rev min-1 = 6.25 m s-1 Fluid properties of air at room temperature, pressure:
