QUESTION 3 A piping system is planned to transport sea water from source point to a processing plant using a 80 cm diameter pipe for the length of 100 m at 30C. The fluid properties of the sea water are p = 1030 kg/m and u = 0.008 kg/m.s. Assume the pipe is restrained by stopper supports along its length. If the flow velocity within the pipe is measured to 1.05 m/s and the pipe is made of smooth stainless steel material, determine: The Shedding frequency in Hz (5 Marks) The shedding natural frequency and the time period (5 Marks) The vibration response of the pipe if the amplitude of the vibration 20 mm is applied and the phase angle is (2 Marks) The maximum values of velocity and acceleration experienced by the pipe.
