two reservoirs with a head difference of 15 m. It is proposed to increase the flow
by 30 % by adding another pipe from the upstream reservoir in parallel and
joining to the main pipe at a suitable location. Assume all pipes are of same
diameter and same friction factor (f=0.02). Determine length of the additional

pipe.

b) Discuss the development of boundary layer over a flat plate. (5)
c) Discuss the phenomenon of separation of boundary layer over curved surface. (5)
