Pressure Drop, Acrylic Diameter Comparison, VenturiAbstract
This research uses experimental method determine Pressure Drop coefficient that occurs Venturi pipes with specimen ratios 1,2, and 3 acrylic tubel diameters 0.4:2.54, 0.8:2.54, and 12:2 .54. By knowing Pressure Drop found three acrylic pipes, we will know how much pressure drop will occur. To find Pressure Drop value, working fluid flowed with flow rate of 0.00002167m3/s, 0.00025m3/s, and 0.00041m3/s at flow rate per minute in venturi pipe and Flowmeter flow measuring instrument. The pressure that occurs onl inlet side (D1) and thel outlet side Venturi pipe (D2) will measured lU manometer. Then, from pressure difference that occurs each flow discharge, Pressure Drop value calculated. From results thils research, foundl that greater discharge, smaller Pressure Drop coefficient, because greater discharge, greater fluid velocity. The Pressure Drop values specimens 1,2, and 3 produce, smaller flow rate, greater drop fluid pressure which can be seen from final results on U manometer.
