The mixture of alcohol passes from Tank 1 to the pump where the pressure changes of the mixture. Then it goes through the pipe segment 1 before entering pipe segment 2. The pipe segment one is 3.7km long with an internal diameter of 10 inches. It has an elevation angle of 2 degrees. The inlet and outlet ambient temperature are 45 and 22 degree Celsius respectively, with a heat transfer coefficient of 5 watt/sqm.K. It has two gate valves, one 90 degree elbow and 2 branched tees. The second pipe segment is characterized by a length of 3.6km and an internal diameter of 10 inches. The pipe is maintained at constant temperature and has a pipe rise of 7 meters. It has two butterfly valves, one 90 degree elbow, and two straight tees. A valve in installed just before the Tank 2 with an opening of 0.134% using a liner characteristic type. It has a 'Pressure drop ratio factor' of 0.5 and 'Pressure recovery factor' of 0.6. The Cv factor is 1500 at 100% opening. The specification of the pumps are given in Table 2 below. Table 2: Pump specification The requirement of the exit stream from tank 2 for further stages of the plant are as follow: Temperature: 21 to 23 degree Celsius Pressure: 16 to 17 bars Phase: Liquid 9) Imagine that the the pump and the valve were removed from the system. Specify if the existing stream from Tank 2 meets the required specifications. 10) Based on the previous question, Explain the technical and the economic impacts of having both the pump and the valve in the system The mixture of alcohol passes from Tank 1 to the pump where the pressure changes of the mixture.
