Q1. The figure shows an elbow in a horizontal pipe used to deflect water at an angle of =40 from the horizontal pipeline. The water is discharged into the atmosphere Pam=101.325kPa and the mass of the water and the elbow 1560kg. Answer the following questions. a) What is the absolute pressure of the water in the pipeline? b) Calculate the magnitude of the resultant force due to change of momentum? (marks 10) c) Does the magnitude of the force calculated in point b increase or decrease with the angle B? (marks 15) your answer with numerical data and an expling ing ? Please support problem (marks 20) Note: The density of water is 1000m3kg. The momentum flux correction factor is 1.03
