Задача по Гидравлике

Determine the excess water pressure forces on the flat wall (AW) and a cylindrical surface (ETS or VVD) rectangular tank with water. Find the magnitude of the forces and their point of application. The decision to perform analytical and graphical manner.
Absolute pressure at the free surface p0 = 120kPA
The water depth h1 = 1.4m, h2 = 2.0m
Radius r = 0.14m
wall width b = 1.7m
The length of the cylindrical surface l = 1.7m
