As an engine operates at 3200 RPM, 0.0012 kg of air–fuel-exhaust residual experience tumble in each cylinder. The radius of tumble rotation is 0.90 cm, and tumble ratio is 1.78.
Calculate:
(a) Tangential velocity at edge of tumble rotation. [m/sec]
(b) Rotational kinetic energy of tumble in one cylinder. [J]
