Question

There are three intermediate storage tanks located at different levels in an oil company.

The discharge lines of tank 1 and tank 2 are commercial steel pipes with an inside diameter of 0.3 m and a length of 1.5 km.

The oil discharged from tank 1 and tank 2 combines at a junction point 1.5 km from both. The product combined at the junction is transferred from the junction point to Tank 3 at a distance of 0.5 km from a commercial steel pipe with a diameter of 0.5 m. There is a 10 m difference between the oil level in Tank 1 and the oil level in Tank 3. There is a 7 m difference between the oil level in Tank 2 and the oil level in Tank 1. Tank 2 is above tank 1.

Calculate the mass flow rate at the beginning of the process. You can get the density of liquid oil as 870 kg / m3 and 0.7 mN-s / m2.

Show all the details of your mathematical approach and equations clearly and obviously. If you have used trial and error method, show the intermediate steps in a chart explaining the algorithm.
