Waste Water Engineering The settling velocity of a spherical particle of diameter less than 0.1 mm as per Stock’s law, is Vs = 218 (Gs – Gw)d [(3T + 70)/100] Vs = 418 (Gs – Gw)d² [(3T + 70)/100] Vs = 418 (Gs – Gw) d [(3T + 70)/100] Vs = 218 (Gs – Gw)d² [(3T + 70)/100] Vs = 218 (Gs – Gw)d [(3T + 70)/100] Vs = 418 (Gs – Gw)d² [(3T + 70)/100] Vs = 418 (Gs – Gw) d [(3T + 70)/100] Vs = 218 (Gs – Gw)d² [(3T + 70)/100] ANSWER DOWNLOAD EXAMIANS APP
