A straight inclined pipeline 300 m long discharges freely at a point 50 m lower than the water surface at intake. The pipe intake projects into the reservoir(ke = 0.8). The first 200 m of the pipe is 350 mm diameter and the remaining 100 m is of 250 mm diameter (kc = 0.21).
(i) find the rate of discharge assuming f=0.06. If the junction point C of the two sizes of the pipe is 40 m below intake water surface level, find pressure head .
(ii) just upstream of C
(iii) just downstream of C. Assume sudden contraction at C
(iv) Verify the head loss across contraction C
