Rake Rake with different bar profiles or different angles of inclination Features - local losses at a rake Learning objectives/experiments - behaviour of open channel flow with reduced flow cross-section -- subcritical discharge -- supercritical discharge - determination of loss coefficients -- effect of the bar profile -- effect of rake inclination Specification [1] rake for the experimental flume HM 162 [2] 3 different bar profiles [3] adjustable bar inclination [4] rake bar spacing can be changed by removing single bars [5] transparent frame with sealing lips Technical data Rake - number of removable bars: 11 - bar inclination: 40°...90°, graduation: 5° Bars - 3 profiles: rectangular, circular, streamlined body - bar material: PVC LxWxH: 375x304x360mm Weight: approx. 15kg
