please answer full question with explanations

Monoethanolamine flows from one tank to another at 55m3/hr as shown below. At point 1 the internal diameter of the pipe is 0.08m and an expansion occurs in the plpe to 0.15m using an expansion fitting. The fluid is pumped to point 2 where the pipe is contracted from 0.15m to 0.08m. The angle of the expansion and constriction fittings is 20. The length between point 1 and point 2 is 12km and the elevatlon achleved is 5m. Moreover, there are 690 standard elbows and 445 standard elbows situated along the plpe between points 1 and 2 . a) Find the pressure drop between point 1 and polnt 2 b) If a pump were to be installed to pump the llquid between the two tanks, llst the extra factors that need to be considered to ensure that the pumpoperates efficlently and achleves the desired purpose
