A system measures dynamic force of an impacting spray of air and water. A pitot-tube
section is aligned to receive a longitudinal flow of impacting air/water spray
in a laterally extending orifice. A first differential pressure transducer is coupled
to the pitot-tube section for producing signals representative of velocity of the
air/water spray at the orifice. A rain gage section adjacent to the pitot-tube
section receives and collects volumes of water of the longitudinal flow of air/water
spray through a laterally extending opening. A second pressure differential transducer
is coupled to the rain gage section to produce signals representative of the volumes
of water collected in the rain gage section. A computer-based control/readout module
receives the velocity representative signals and water volume representative signals
for indicating the magnitude of dynamic force attributed to impacting air/water
spray in the opening.
