HM 164 Open Channel And Closed Channel Flow Didactic Equipment Vocational Education Equipment Fluid Mechanics Lab Equipment
Flow processes on different structures in open and closed channel flows; losses at inlet and outlet Features - flow processes in the open channel: gate, sill and various weirs - flow processes in the closed channel: pipe flow - closed water circuit with tank and pump Learning objectives/experiments - open channel -- flow over control structures: broad-crested weir, narrow-crested weir, ogee-crested weir with ski jump spillway, sill -- discharge under a gate -- hydraulic jump - closed channel -- pipe flow with constant and variable flow cross- section -- measurement of static pressure and total pressure -- calculation of the flow velocity Specification [1] investigation of flow processes in the open and closed channel [2] experimental flume with upper limit, made of transparent material [3] height-adjustable sill in the bottom of the experimental flume [4] water level adjustable via plate weir at the water outlet [5] simple conversion from open to closed channel [6] control structures for experiments in the open channel: broad-crested weir, narrow-crested weir, ogee-crested weir with ski jump spillway, sill, gate [7] fully flowed through experimental section and change in cross-section over sill for experiments in the closed channel [8] closed water circuit with supply tank and pump [9] transparent measuring tubes for measuring static pressure and total pressure Technical data Experimental section - length: 1,1m - cross-section WxH: 40x300mm Supply tank: 70L Pump - power consumption: 250W - max. flow rate: 150L/min - max. head: 7,6m 230V, 50Hz, 1 phase 230V, 60Hz, 1 phase; 120V, 60Hz, 1 phase UL/CSA optional LxWxH: 1900x800x1350mm Empty weight: approx. 150kg
