“…Berbagai pendekatan telah digunakan untuk mengukur distribusi ukuran partikel [7]. BWM telah berhasil diaplikasikan dalam menentukan distribusi ukuran partikel yang berukuran 5 μm -100 μm, seperti distribusi ukuran partikel pasir silika, serbuk kalium karbonat, butiran kaca barium titanat [5], dan semen [8]. BWM merupakan metode pengukuran distribusi ukuran partikel yang murah, praktis, dan cukup akurat [5].…”

“…Hasil penelitian ini juga sebanding dengan penelitianTambun et al (2016) yang menyatakan bahwa hasil penentuan distribusi ukuran partikel semen menggunakan BWM dengan etanol sebagai mediumnya paling mendekati hasil pengukuran menggunakan metode settling balance dibandingkan dengan jenis cairan lainnya[8]. Tabel 2 menunjukkan hasil penentuan distribusi ukuran partikel serbuk kaca menggunakan metode settling balance dan BWM dengan berbagai variasi jenis cairan.…”

Particle size distribution is one of the important physical parameters in industry. A new method has been developed, the buoyancy weighing-bar method to determine the particle size distribution. This study examines the application of the buoyancy weighing-bar method for the determination of the particle size distribution of glass powder. Measurements were made by varying the type of liquid, the type of rod, and the size of the rod length. From this study, it was obtained that the best condition in determining the particle size distribution of glass powder is using aluminum rods with a length of 210 mm in 96% ethanol. The results of determining the particle size distribution of glass powder by using the buoyancy weighing-bar method at the best conditions are comparable to the results of determining the particle size distribution obtained using the settling balance method.

“…In accordance with the principal of the ballasting weight (BW) method [3], the cement's particle size distribution was determined using the buoyancy weighing-bar method. The density change in a suspension due to particle migration was measured by weighing the buoyancy against a weighing-bar hung in the suspension; then, the particle size distribution was calculated using the length of the bar and the time-course change in the mass of the bar [10]. In terms of the BW method, the variable buoyancy engine (VBE) was used to vary the buoyancy of an underwater vehicle to implement the depth control process of the linear quadratic regulator method.…”

Net buoyancy changes affect hovering performance and increase the extra energy consumption of deep-sea intelligent floats (DIFs) at different submergence depths. To improve the adjustment efficiency of net buoyancy changes and solve the extra energy consumption problem at different submergence depths, this study proposes a combination model of ballasting weight (BW) and minimum oil content for DIFs based on the BW method. The proposed model is accurately designed by combining an exponential function model of actual density distribution in the oceans and the deformation of a DIF hull that resulted from compressibility and thermal expansibility. Given that the adjustment process of the net buoyancy changes should be approximated for actual deployment, the model establishes the compressibility balanced relationship between the DIF hull and actual seawater. The feasibility of the proposed model is validated through hyperbaric tank system and at-sea experiments. Experimental results show that the relationship between the net buoyancy changes of DIF and pressure is nonlinear. The BW changes fluctuate between 0.05 and 0.15 g by increasing the diving depth by 1 m. For the influence of the BW on the submergence depth error, the scope of the depth error ratio is 2.2% to 2.8% from the predefined depth of 100-4200 m. Analysis results provide a basis for the establishment of an optimal net buoyancy adjustment scheme for DIFs. INDEX TERMS Ballasting weight (BW), deep-sea intelligent float (DIF), hyperbaric tank system, minimum oil content (MOC), net buoyancy change.
