A semi-cylindrical concrete structure having a radius of 3 m and length of 5 m is rested on ground. Wind (air having a density ρ=1,2 kg/m3 ) at a free-sream speed of 10 m/s with an atmospheric pressure of 100 kPa far upstream the structure blows over the structure. The air entrance to the structure is at ground level corresponding to the forward stagnation point . Since the magnitude of minimum pressure is acting on the top of the structure determine the magnitude of lift force due to the pressure difference in vertical direction .Assume flow potential
