Classification: CPC G | IPC G

Claim 4:
5. A method for measuring flow characteristics, the method comprising:
providing a sample material for measurement of flow characteristics;
passing the sample material through a flow restriction passage;
controllably moving a plurality of movable fins into and out of the flow restriction passage;
measuring flow or flow resistance through the flow restriction passage with the movable fins moved into and out of the flow restriction passage;
using a pump to providing flow from a flow supply source through the flow restriction passage; and
measuring power used to power the pump sufficiently to maintain a predetermined flow through the flow restriction passage, and thereby provide a comparison between the power required to maintain the predetermined flow with the movable fins extended into the flow restriction passage and the power required to maintain the predetermined flow with the movable fins not extended into the flow restriction passage.
