Verified answer

engineering

An open rectangular settling tank contains a liquid suspension that at a given time has a specific weight that varies approximately with depth according to the following data:

\begin{matrix}\text{h (m)} & \mathrm{\gamma (N/m^{3})}\\\text{0} & \text{10.0}\\\text{0.4} & \text{10.1}\\\text{0.8} & \text{10.2}\\\text{1.2} & \text{10.6}\\\text{1.6} & \text{11.3}\\\text{2.0} & \text{12.3}\\\text{2.4} & \text{12.7}\\ \text{2.8} & \text{12.9}\\\text{3.2} & \text{13.0}\\\text{3.6} & \text{13.1}\\\end{matrix}

The depth h = 0 corresponds to the free surface. Determine, by means of numerical integration, the magnitude and location of the resultant force that the liquid suspension exerts on a vertical wall of the tank that is 6 m wide. The depth of fluid in the tank is 3.6 m.
