Type: Diagram
Date: no date
Source: Descriptive Catalogue

Description: This cross-section diagram of part of the Pillsbury "A" Mill shows how water was transported to the turbines that were used to run the machinery in the mill.

Diagram of a Chute Dropping Water to a Turbine

Activities:

  1. The turbine is located at the bottom of the water-filled pit or flume. Knowing what you do about waterwheels and turbines, what is the purpose of the flume?

    Answer:
  3. Can you tell from the source about how big this turbine is?



    Answer:
  4. Beside the words that tell you this flume was at a mill in Minneapolis (across from St. Anthony), what else might be a clue to where this mill was located?
