Question:
The “spherical” Pitot probe shown is used to measure the flow velocity in hot water (ρ = 965 kg/m3). Pressure taps are located at the forward stagnation point and at 90° from the forward stagnation point. The speed of fluid next to the surface of the sphere varies as 1.5 V0 sin θ, where V0 is the free-stream velocity and θ is measured from the forward stagnation point. The pressure taps are at the same level; that is, they are in the same horizontal plane. The piezometric pressure difference between the two taps is 3 kPa. What is the free-stream velocity V0?
