Title: A simple example of resistance in pipe flow

Description: Identical tanks are being drained through outlet pipes of various lengths. Of the four different pipe lengths, the shortest tube drains the quickest. The discharge rate is influenced by the viscous losses in the different length pipes. For laminar flow through the tube and ignoring entrance losses and entry flow, the flow rate is inversely proportional to the straw length.
