WebUsing Equation 2, we calculate an average weathering rate (R d) of 0.22 mg/mg/y (Table S1 in Supporting Information S1). We estimate f α for the hostrock using the measured value of ( 234 U/ 238 U) of 0.9003 ± 0.0014 and average U concentrations in hostrock ground mass measured by laser ablation (905 ppb) and dripwater (13.7 ppb), following Equation 5 . WebThe interfacial area per unit volume of dispersion, in a gas-liquid contactor, for fractional hold up of gas = 0.1 and gas bubble diameter = 0.5 mm is given by (in m2/m3) A. 500. B. …
