Water from a Reservoir through a main canal is connected to a branch canal over an embankment by means of tube of 90 mm diameter. The length of pipeline up to the summit is 25 m and the total length is 65 m. Entry loss may be assumed as one-half of the velocity head in the pipe. Assume friction factor, f = 0·03. Water surface elevation in the branch canal is 10 m below that of the main canal. If the total quantity of water required to be conveyed is 0·06m3 /s, how many pipelines are needed for effective delivery of water ? What is the maximum permissible height of the summit above the water

Water surface elevation in the branch canal is 10 m below that of the main canal. If the total quantity of water required to be conveyed is 0·06m3 /s, how many pipelines are needed for effective delivery of water ?
What is the maximum permissible height of the summit above the water level in the main canal so that the water pressure at summit may not fall below 20 kN/m2? Explain the losses that were encounted when the water was flowing through the tube. ( absolute, thebarometric reading being 10 m of water)
