SUMMARYThe purpose of this lab was to analyze the behaviour of water through a sluice gate as well as a hydraulic pump, to evaluate the validity of techniques learned in class. The flow of water was analyzed at 3 points: in the upstream reservoir, at supercritical flow, and at subcritical flow. Supercritical flow can cause corrosion to the machine, and so the water is forced through a hydraulic pump downstream, after which the water is at subcritical flow, and will cause no damage. The assumptions to be made in this lab include frictionless flow, steady flow, and no energy or heat loss. These assumptions must be made in order to apply the techniques learned in class.LIST OF SYMBOLSConstants:Patm= 101325 kPaρAIR = Density of air = 1.225 kg/m3ρ WATER= Density of water = 1000 kg/m3g = acceleration due to gravity = 9.81 m/s2w = width of channel = 6.125 inVariables:H = Head of Fluid (m)F = Force (N) P = Pressure (Pa)ṁ = mass flow rate (kg/s)Q = volumetric flow rate (m3/s)V = velocity (m/s)Z = elevation of fluid (m)A = area (m2)
