Electricity and Water Analogy

  1. Jan 20, 2008 #1
    Consider the following water circuit: water is continually pumped to high pressure by a pump, and then funnelled into a pipe that has lower pressure at its far end (else the water would not flow through the pipe) and back to the pump. Two such circuits are identical, except for one difference: the pipes in one circuit have a larger diameter than the pipes in the other circuit. Through which circuit is the flow of water greater?


    Small pipe
    Large pipe

    If they didnt tell me about the velocity, how am i going to know about this??

    I suppose this is homework? They do give you enough information to answer it. Hint: Velocity itself is not the critical issue.
