The rate of flow in this pipe system is 0.05 m/s. The pressure at point 2 is measured to be 238 Pa. The pipe is laid on a downslope with pt 1 at a height of 115 m above pt 2. All the pipes are galvanized iron with roughness value of 0.15 mm. Determine the pressure at point 1. Include minor losses at the sudden contraction where the loss coefficient is 0.05. Ignore minor losses at the expansion. Use v= 1.141 x 10 m/s. 1 A Pipe Name Pipe A Pipe B Pipe C B Length (m) 280 350 450 Diameter (mm) 120 180 120 20
