b) Dalam proses penapaian, bekalan oksigen (O2) adalah penting untuk mengekalkan produktiviti baik produk yang ditapai. Biasanya, kaedah pengocakan digunakan untuk menghasilkan buih-buih udara yang mengandungi O2 untuk meningkatkan penyebaran O2 dalam medium berair kepada mikroorganisma penapaian . In fermentation process, the supply of oxygen (O2) is essential to maintain good productivity of fermented products. Usually, agitation method is used to produce air bubbles containing O2 to enhance diffusion of O2 in the aqueous medium to the fermentation microorganisms. (i) Dengan menganggap satu tangki pencerna sisa cecair kilang kelapa sawit (POME) dengan suhu operasi 37C dan tekanan 1atm, dengan agitasi buih udara, tentukan nombor Schmidt untuk buih udara dalam larutan POME. By considering a digester tank of Palm oil Mill Effluent (POME) with operating temperature of 37C and pressure of 1 atm, with agitated air bubbles, determine the Schmidt number for air bubbles in POME solution. Jadual 1 menyenaraikan sifat POME dan udara pada 37C Table 1 lists the properties of POME and air at 37C (3 markah/marks) Dengan mengandaikan udara pada suhu 37C dan 1atm digelembungkan di dalam cecair POME dengan purata diameter gelembung 100m, hitung pekali pemindahan jisim gelembung udara di dalam POME. By assuming air at 37C and 1atm is bubbled in POME liquid with mean bubble diameter of 100m, calculate the mass transfer coefficient of air bubble in POME. (5 markah/marks) Kirakan kadar maksimum penyerapan O2 dari gelembung udara di dalam cecair POME dengan mengandaikan kepekatan awal O2 dari gelembung udara di dalam cecair POME adalah 2.26104kmol/m3. Calculate the maximum rate of absorption of O2 from air bubble in POME liquid by assuming the initial concentration of O2 from air bubbles in POME liquid is 2.26104kmole/m3
