Q. The settling velocity of a spherical particle of diameter less than 0.1 mm as per Stock's law, is (Solved)
1. Vs = 418 (Gs- Gw)d [(3T + 70)/100]
2. Vs = 418 (Gs - Gw)d² [(3T + 70)/100]
3. Vs = 218 (Gs - Gw)d² [(3T + 70)/100]
4. Vs = 218 (Gs - Gw)d [(3T + 70)/100]
- b. Vs = 418 (Gs - Gw)d² [(3T + 70)/100]
