Question

(a) Derive an expression from the fundamentals for the loss of head due to Friction in a pipe line. Why this loss is called Major loss ?

(b) A straight $25\text{ cm}$ diameter pipeline $5\text{ km}$ long is laid between two reservoirs having a difference in level of $40\text{ m}$. To increase the capacity of the system an additional $2.5\text{ km}$ long $25\text{ cm}$ pipe is laid parallel from the first reservoir to the midpoint of the original pipe. Assuming $f = 0.025$ for both the pipes find the increase in discharge due to installation of the new pipe.
