please answer the question I need urgently

(b) A piping system shown in Fig. 2 has been constructed from 75mm galvanized iron pipe. All flow rates are high enough that the flow may be considered in fully rough zone. Minor losses may be neglected. Determine the gauge pressure at section 2 , in terms of flow rate Q2. Find the unknown flow rates Q1,Q2,Q3 as fractions of the inlet flow rate, Q0. All flow rates are expressed in m3/s The fluid is water
