Two pipes 1 and 2 having the following properties are connected in series: Pipe 1 - Length = 1500m, Diameter = 850mm f= 0.025 Pipe 2 - Length = 1200m, Diameter = 650mm f= 0.020 It is required to replace these two pipes with a single pipe whose length is 2700m. Assuming that the friction factor for the new pipe is 0.015, what is the required pipe diameter?

The water is flowing through a pipe having diameters 30 cm and 21 cm at sections land 2 respectively. The rate of flow through pipe is 40 litres/s. The section 1 is 7 m above datum and section 2 is 3 m above datum. If the pressure at section 1 is 37 N/cm? , find the following by neglecting losses: (ENTER ONLY THE VALUES BY REFERRING THE UNIT GIVEN IN BRACKETS) ) Area of cross section of section1 (unit in m?) = Area of cross section of section2 (unit in m?) = velocity at section 1 (unit in m/s) = velocity at section 2 (unit in m/s) = (ii) difference in datum head (Unit in m) = Pressure head at section 1 (Unit in m) = pressure head at section 2 (unit in m) =
