Two pipes are connected in series with a diameter ratio of 2:5. If the flow velocity in the smaller diameter pipe is 12 m/s, determine the head loss due to (a) sudden contraction, (6) sudden enlargement.

Two reservoirs with elevation difference of 10 ft are connected by a 6-in-diameter pipe ( = 0.032). The pipe is having a flush entrance and submerged exit. Determine the flow rate if the pipe length is 110 ft. If the last 10 ft of pipe length is replaced by a 10° conical diffuser, compute the flow rate.
