Masonry wall construction

Masonry walls of various sorts are utilized in building construction. Masonry walls are the most enduring feature of any structure or building. It separates a structure from the outside world. In masonry construction, the common masonry materials used are building stone, brick, cast stone, glass block, and concrete block. Masonry construction is a type of construction that has the highest durability.

Someone can help me with this please
The coefficient of permeability below a dam is 12 m/day. The water in the upstream side is 32 meter higher than on the downstream side (level with the ground). To estimate the seepage below the dam, a flow net is graphically drawn such that the number of potential drops, Nd = 8 and the number of flow channels Nf = 3. The base of the dam is founded 1.8 m below the ground. Between the heel and the toe of the dam, a distance of 32 meters, there are 6 potential drops. a. Estimate the seepage per meter length of the dam in liters per minute. (IN EXPONENTIAL FORM AND IN 2 DECIMAL PLACES) b. Determine the uplift pressure at the heel in kPa. (IN 2 DECIMAL PLACES) c. Determine the uplift pressure at the toe in kPa. (IN 2 DECIMAL PLACES)
