Water at 20°C is flowing through an 8 cm diameter pipe from reservoir 1 to reservoir 2 as shown in the figure. The pipe contains rounded sharp exit from reservoir 1 and rounded sharp entrance in the inlet of reservoir 2. The pipe length is 10 m and its relative roughness ɛ/d = 0.0001. Both reservoirs are pressurized by compressed air where P₁ = 150 kPa and P₂ = 100 kPa. If reservoir 1 elevation is 12 m and reservoir 2 elevation is 8 m find the flow rate through the pipe in m³/h. 8 m Air 2 Air Rounded sharp 1 12 m entrance Rounded sharp exit 10 m
