Claim 6:
7. A method for measuring fluid flow velocity, comprising:
translating a flexible tube to be adjacent to and in fluid communication with a portion of a plurality of fluid outlets, each one of the plurality of fluid outlets having a cross section defining an outlet area, the flexible tube having a cross section defining a flexible tube area that is larger than the outlet area of each fluid outlet;
receiving, via a pressure transducer tuned to measure fluid speeds having a Reynolds number less than 100, a portion of a fluid flow from the portion of the plurality of fluid outlets via the flexible tube;
generating, by the pressure transducer, a signal corresponding to a pressure of the fluid;
determining, by a controller, an experimental pressure value of the portion of the fluid flow based on the signal;
determining, by the controller, an aggregated average differential pressure of the fluid; and
calculating, by the controller, a corrected flow velocity of the fluid flow based on the aggregated average differential pressure by:
determining a fluid velocity of the fluid at an outlet measuring portion,
applying Bernoulli's equation using a model pressure to determine a calculated velocity,
determining a correction factor based on the fluid velocity and the calculated velocity, and
applying the correction factor to the experimental pressure value.
