A stratified soil deposit consists of three horizontal layers. Layer 1 has thickness $2.0\text{ m}$ and $K_1 = 5\text{ m/day}$. Layer 2 has thickness $3.0\text{ m}$ and $K_2 = 10\text{ m/day}$. Layer 3 has thickness $5.0\text{ m}$ and $K_3 = 2\text{ m/day}$. The equivalent hydraulic conductivity for flow parallel to the bedding planes ($K_h$) in $\text{m/day}$ is ________ (round off to 1 decimal place).
