A study was performed on a laser-induced shock wave plasma generated on high concentration Au-Ag-Cu alloys by a Q-switched Nd-YAG laser of 4.8 mJ under reduced air pressure of 2 Torr. It was found that the total emission intensity of the secondary plasma is proportional to the intensity of the primary plasma, Assuming linear proportionality between the intensity of the primary plasma and the number of atoms vaporized from the target, it is proposed that ...

Kebakaran stasiun pompa bahan bakar umum akibat nyala uap bahan bakar tahun 2020 terekam 38 kali di wilayah Indonesia. Konsentrasi uap bahan bakar yang flamabel pada area diantara batas bawah flamabilitas (Low Flammability Level, LFL) dan batas atas flamabilitas (Upper Flammability Level, UFL) merupakan faktor penyebab kebakaran. Tujuan penelitian: perancangan peralatan pengujian LFL bensin dengan metoda tabung menggunakan evaporasi internal untuk menghasilkan uap bensin. Alat ukur berupa tabung kaca vertikal d= 80 mm t= 300 ...
