A company needs to decide which option is the most advantageous, in terms of emptying time and head loss, to flow a load of 3 m of water from one reservoir. The first option would be through a small circular hole 0.3 m in diameter, and the second option would be to attach a long external nozzle of equal dimension to this orifice. Determine which of the options sought is the shortest emptying time and the least head loss, justify the results found and indicate which option should be chosen. Data Provided: Discharge coefficiente (orifice) = 0.61; Contraction Coefficient (orifice) = 0.62; Discharge coefficent (nozzle) = 0.82; Contraction Coefficient (nozzle) = 1; Reservoir area = 5m²

Question

A company needs to decide which option is the most advantageous, in terms of emptying time and head loss, to flow a load of 3 m of water from one reservoir. The first option would be through a small circular hole 0.3 m in diameter, and the second option would be to attach a long external nozzle of equal dimension to this orifice.
Determine which of the options sought is the shortest emptying time and the least head loss, justify the results found and indicate which option should be chosen.


Data Provided:
Discharge coefficiente (orifice) = 0.61;

Contraction Coefficient (orifice) = 0.62;

Discharge coefficent (nozzle) = 0.82;

Contraction Coefficient (nozzle) = 1;

Reservoir area = 5m²
