The pressure in the wake of a bluff body is approximately equal to the pressure at the point of separation. The velocity distribution for flow over a sphere is V = 1.5 V₀ sin θ, where V₀ is the free-stream velocity and θ is the angle measured from the forward stagnation point. The flow separates at θ = 120°. If the free-stream velocity is 100 m/s and the fluid is air (ρ = 1.2 kg/m³), find the pressure coefficient in the separated region next to the sphere. Also, what is the gage pressure in this region if the free-stream pressure is atmospheric?
