Abstract

Profil asimetris adalah distribusi kecepatan aliran pada penampang melintang pipa yang acak dan alirannya belum berkembang mantap. Aliran asimetris menyebabkan timbulnya galat hingga 11% pada hampir semua alat ukur flowmeter. Solusi agar pengukuran aliran pada fluida berprofil asimetris tetap akurat adalah dengan mengetahui langsung profil kecepatan aliran karena mampu memberikan informasi distribusi kecepatan aliran dengan tepat. Menggunakan Hot-wire Anemometer, mengoptimalkan penempatan lokasi pencuplikan data pada penampang melintang pipa dan memanfaatkan metoda interpolasi kubik, diperoleh hasil pengukuran yang akurat ketika mengukur aliran asimetris dengan galat rata-rata adalah 1,96 % dan profil rekonstruksi yang diperoleh menyerupai profil yang diukur.

Abstract

Electrolysis is a method used to describe the composition of air. electrolysis converts air bonds (H2O) into its constituent compounds flammable Hydrogen and Oksigen which help the combustion process. Water electrolytic devices are called HHO generators, HHO generators use pure water electrolysis, the results of the meeting between H2 and O2 will be used as alternative fuels in meeting renewable energy needs. This research uses a HHO generator. Testing the performance of the HHO generator is done experimentally on a laboratory scale. The first stage is making a dry type HHO generator using SS316L plate. The size of the plate is 70 mm x 70 mm, the center of the plate is punched Ø 12 mm, the top and the bottom of the plate are perforated Ø 10 mm. The HHO generator consists of  5 cells and 4 neutral plates for each cell by agreeing 5, 7 and 9 grams of KOH for 1 liter of distilled water. The results of the production of HHO gas produces a large amount of H2 and O2 which flows in units of minutes at a volume of 500 ml. HHO gas production parameters will depend on current, power and efficiency will increase from each of the above variables. Measurements use special measurement tools to distinguish which are quite significant
