Chemical Engineering Fluid Mechanics Question.
Please help
[b] Initially, 2 spherical particles with same position fall into water. The particles have same final terminal velocity. The specifications of the spheres are given in Table Q.3.[b]. What is the distance between them when : 2 zarah sfera yang pada mulanya berada pada kedudukan yang sama, telah jatuh ke dalam air. Zarah-zarah tersebut mempunyai halaju tamatan akhir yang sama. Spesifikasi sfera-sfera tersebut ditunjukkan dalam Jadual S.3.[b]. Apakah jarak antara zarah-zarah tersebut jika : [i] all the particles achieve terminal velocity of 99% semua zarah mencapai 99% halaju tamatan [ii] any particle achieves terminal velocity of 99%. mana-mana zarah mencapai 99% halaju tamatan. Assume that Stoke law is valid for this case. Anggap hukum Stoke dapat digunapakai bagi kes ini. [14 marks/markah] Table Q.3.[b]. Jadual S.3.[b] Density (kg/m) Viscosity (mNs/m) Diameter (um) Ketumpatan (kg/m) Kelikatan (mNs/m) Spherical 1 (SI) 1900 42 Sfera 1 (S1) Spherical 2 (S2) 3700 Sfera 2 (S2) Water 1000 1 Air ...5/- D2 [b] Initially, 2 spherical particles with same position fall into water.
