please answer the question I need urgently

(a) Water is flowing from a higher reservoir to a lower reservoir (Fig. 3), elevation difference 30m. The total length of the galvanized iron pipeline is 80m. The pipeline contains three fully open globe valves and two 90 standard elbow. Determine the smallest standard pipe size that can be used to deliver water at 2.65m3/min. Assume that standard sizes for the pipe increase in 12.5m steps from 25mm to 75mm, increase from there in 25mm steps to 150mm. Loss coefficients for entrance =0.5, each elbow =0.3, each globe valve =6, exit =1. Assume density of water is 1000kg/m3 and viscosity of water is 103Pa.s. (b) Also Draw the Energy grade line and Hydraulic grade line
