An unconfined fine sand aquifer has a base elevation of 50 ft (15.2 m). From elevation 50 to 68 ft (15.2 to 20.7 m), the average horizontal nydraulic conductivity is 0.8 ft/day (0.24 m/day), and from 68 to 95 ft (20.7 to 29.0 m) the average horizontal hydraulic conductivity is 3.0 t/day (0.91 m/day). Calculate the transmissivity of the saturated portion of the aquifer when the water table is at (a) elevation 75 ft (22.9 m), and ´b) at elevation 85 ft (25.9 m).

Hydraulic conductivity question 

An unconfined fine sand aquifer has a base elevation of 50 ft (15.2 m).
From elevation 50 to 68 ft (15.2 to 20.7 m), the average horizontal
hydraulic conductivity is 0.8 ft/day (0.24 m/day), and from 68 to 95 ft
(20.7 to 29.0 m) the average horizontal hydraulic conductivity is 3.0
ft/day (0.91 m/day). Calculate the transmissivity of the saturated portion
of the aquifer when the water table is at (a) elevation 75 ft (22.9 m), and
(b) at elevation 85 ft (25.9 m).
