7. [2 points] It is given that in the following configuration, the gage pressures at 1 and 2 are P₁ = 100 kPa, and P₂ = 125 kPa, respectively; A₁ = 5 × 10-4 m² and A₂ = 2 × 10-3 m²; and V₂ = 1 m/s. Elevation difference between the two points is 2 m. (a) [1.5 point] Find the direction in which the flow of water (p = 1000 kg/m³) is occurring, that is, is it from 1 to 2 or is it from 2 to 1. Clearly show how you know, using appropriate fluid mechanics based analysis. (b) [0.5 point] Are there frictional losses present in this configuration? Answer Yes or No. How do you know? 2m Answer Direction of flow = Losses present? =
