These 2.5m and 5m units provide channels with adjustable slope and transparent acrylic sides for full visibility of the ﬂow characteristics. Test models plus an inclinometer and surface proﬁle measuring instrument are used to investigate the ﬂow of water along an open channel and to verify the Chézy equation and Mannings friction factor.
Additional experimental equipment provided with the 5m channel includes a pitot-static
tube, dam spillway, Ogee (i.e. overﬂow) weir with manometer, Crump weir and Parshall ﬂume.
