Problem $2(20$ Points$)$

Figure $1$ shows the flow net of a sheet$-$pile wall which is embedded $12ft$ into a pervious soil layer overlying the bedrock.

a$.$ Calculate the seepage in the permeable layer.

b$.$ What is the total head of water $(h_t)$ at points $w$ and $x$ assuming the datum at the bedrock?

c$.$ Determine the pressure head of water $(h_p)$ at points $w$ and $x.$

Shade the element in the flow$-$net that maintains the largest water velocity.
