Coconut water (SG = 1.105) enters the middle section of a vertical distillation column as it flows down a copper reducing bend (Pcu = 8960 kg/m?, Vrotal = 0.315 m2, and void fraction (fvoia) = 0.975) that connecting a 10.16-cm pipe and a 5.08-cm pipe. The outlet pressure of the bend is 825 kPa. For the head loss of bend, it can be calculated as hị = Kv² /2g, where the resistance coefficient (K) equals to 3.5 and the velocity is the inlet velocity for this case. The fluid flow rate is 0.025 m/s. V1 Fp. l Wew Wbend 0.37 m Fp2 V2 (a) Calculate the velocity at point 1 and 2. Subsequently, identify the magnitude and direction of resolved components of all velocities. (4 Marks) (b) Calculate the head loss of the piping system and the density of the coconut water. (2 Marks) (c) By performing suitable conservation of energy principle, compute the pressure acting on the point 1. Calculate all the pressure forces. Subsequently, identify the magnitude and direction of resolved components of all pressure forces. (4 Marks) (d) Calculate the required weights for the linear momentum analysis.
