Jet Trajectory and Orifice Flow — MOE Lab Tender Details

Jet Trajectory and Orifice Flow

Shows vertical flow and horizontal jet trajectory through different orifices (nozzles)

Experiments
Determination of the contraction and velocity coefficients; hence the calculation of the discharge coefficient
Determination of the actual discharge coefficient by measurement of flow rate for comparison against calculated value
Determination of the above over a range of flow rates to show the influence of Reynolds number
Determination of discharge characteristics (jet trajectory) for an orifice mounted in the side of a vertical tank and comparison with simple theory

Specifications
Comprises a clear acrylic cylinder on a stand, with apertures in the base and on the side of the cylinder for the insertion of orifices/nozzles
Nominal dimensions of cylinder 400 mm x 160 mm diameter. Approx 8 L capacity
A plotting board fixed to the side of the cylinder with 10 adjustable rods allows the shape of the jet trajectory to be recorded
