To minimize the computational consu

To minimize the computational consumption, all the two simulation piping models have been meshed with shell ele- ments. The simulation is using the actual pipe geometry assigned with shell elements and a thickness is assigned to the shell elements. The thickness of suction tube and dis- charge tube are 1.2 and 0.8 mm respectively. As the mate- rial used is copper-phosphorus alloy, the material property particularly elasticity modulus is obtained from the tensile test on the material specimens and they are tabulated in Ta- ble 1 below. The density is calculated from the physicalmass of the pipeline.
