An absorbing dynamometer acts as a load that is driven by the prime mover that is under test (e.g. Pelton wheel). The dynamometer must be able to operate at any speed and load to any level of torque that the test requires.
Other factors which may contribute to flooding include: 1  volume, spatial distribution, intensity and duration of rainfall over a catchment; 2  the capacity of the watercourse or stream network to convey runoff; 3  catchment and weather conditions prior to a rainfall event; 4  ground cover; 5  topography; and. 6  tidal influences.
Do not change gear because this can also cause water to be sucked back through the exhaust (due to the change in engine speed and manifold depression). Another potential cause of damage in floods is a cracked catalytic converter (âcatâ).
