Calculate form-resistance coefficient and form loss in the following pipe specials if the pipe discharge is 0.15 m3 /s: (a) Pipe bend of 0.3-m diameter, bend radius of 1.0 m, and bend angle as 0.3 radians. (b) A 2/3 open sluice valve of diameter 0.4 m. (c) A gradual expansion fitting (enlarger) of end diameters of 0.2 m and 0.3 m with transition length of 0.5 m. (d) An abrupt contraction transition from 0.4-m diameter to 0.2-m diameter.
