Two points in the same confined aquifer are located 10,000 meter apart. Point 1 is 100 m below mean sea level and point 2 is 50m below mean sea level. The fluid pressure at point 1 is 9.0 x 105 N/m2 and at point 2, it is 6.1 x 105 N/m2

Assume that the mean sea level is at zero datum. Assuming that the gravitational constant g is 9.80 m/s2 and the density of water is = 1000 kg/m3

The hydraulic gradient and flow direction between point 1 and point 2 are

A)0.02, from point 1 to point 2

B)0.002, from point 2 to point 1

C)0.0002, from point 2 to point 1

D)0.0023 from point 1 to point 2
