Two kilograms of water undergo a process from an initial state where the water is saturated vapor at 120°C, the velocity is 30 m/s, and the elevation is 6 m to a final state where the water is saturated liquid at 10°C, the velocity is 25 m/s, and the elevation is 3 m. Determine in kJ:a) the exergy at the inital stateb) the exergy at the final state,c) the change in exergyLet To = 25°C, Po =1 atm, and g = 9.8 m/s2 ### Figure Description for Educational Website**Title: Fluid Dynamics Analysis**The provided illustration depicts an analysis of fluid dynamics involving both saturated vapor and liquid.1. **Point 1: Saturated Vapor at 120°C** - At the first marked point (Point 1), there is a flow of saturated vapor. - The temperature of the vapor is 120°C. - The velocity of the vapor flow at this point is 30 m/s. - Point 1 is situated 6 meters above the reference level.2. **Point 2: Saturated Liquid at 10°C** - At the second marked point (Point 2), there is a flow of saturated liquid. - The temperature of the liquid is 10°C. - The velocity of the liquid flow at this point is 25 m/s. - Point 2 is situated 3 meters above the reference level and 3 meters below Point 1.**Reference Conditions:** - Ambient pressure (\(p_b\)) is 1 atmosphere (atm). - Reference temperature (\(T_0\)) is 25°C. - Gravitational acceleration (\(g\)) is 9.8 meters per second squared (m/s²).**Diagram Details:**- The figure highlights the vertical placement of the two points: Point 1 is higher than Point 2.- Both points have annotations indicating the flow direction and velocity with arrows.- The reference level is marked at the bottom with axis notation, showing a vertical direction labeled as \(z\).This setup is typical in studying the behavior and properties of different phases of a substance in fluid mechanics and thermodynamics, where understanding velocity, temperature, and position are crucial for applications such as heat exchangers, distillation columns, and refrigeration cycles.
