Question

Water at 20 C is steadily flowing through a diverging pipe section that is inclined by an angle of 30° with respect to the horizontal (See the figure) The total testing section length is 20 m long with an initial pipe diameter of 10 mm (Section 1) and final diameter of 20 mm (Section 2). The small diameter section shows a gage pressure of 100 kPa and average flow velocity 10 m/s. Other values will be obtained by reaching complete equilibrium conditions. Density ?? 12-1.0, ?? ?? tilt angle 20 m D2 20 mm ?-998 kg/m3, g-9.81 m/s 1.0 and no friction losses. P1 100 kPa v1 10 m/s D1 10 mrm Use conservation of mass, energy and lineal momentum equations (if needed) to complete the missing values of the following table (showing the equations used, as well as the corresponding values and results with units): Section2 0.02 Units Section 1 0.01 Parameter Diameter (D) Elevation (Z) Cross Sectional Area (A) rn 10 Average Velocity (V) Volumetric Flow Rare Mass Flow Rate m's kPa 100 Gage Pressure (P) Potential Head Velocity Head Pressure Head Total Mechanical Head Im Fluid Mechanical Power Watts Lineal Momentum Flux
