- Question : EX1 - Calculate head loss in a 500-m-long CI pipe of diameter 0.4 m carrying a discharge of 0.2 m3/s. Assume water temperature equal to 208C.
- Question : EX2 - Calculate form-resistance coef?cient 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 ?tting (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.
- Question : EX3 - The pump of a 500-m-long rising main develops a pressure head of 30 m. The main size is 0.3 m and carries a discharge of 0.15 m3/s. A sluice valve is ?tted in the main, and the main has a confusor outlet of size 0.2 m. Calculate terminal head.
- Question : EX4 - Water is transported from a reservoir at higher elevation to another reservoir through a series of three pipes. The ?rst pipe of 0.4-m diameter is 500 m long, the second pipe 600 m long, size 0.3 m, and the last pipe is 500 m long of diameter 0.2 m. If the elevation difference between two reservoirs is 30 m, calculate equiv- alent pipe size and ?ow in the pipe.
- Question : EX5 - Water between two reservoirs is transmitted through two parallel pipes of length 800 m and 700 m having diameters of 0.3 m and 0.25 m, respectively. It the elevation difference between two reservoirs is 35 m, calculate the equivalent pipe diameter and the ?ow in the pipe. Neglect minor losses and water columns in reser- voirs. The equivalent length of pipe can be assumed as 600 m.
- Question : EX6 - A CI pumping main of 0.4 m in size and length 1500 m carries slurry of average sediment particle size of 0.2 mm with mass densities of particle and ?uid ratio as 2.5. If the volumetric concentration of particles is 30% and average temperature of water 208C, calculate total head loss in the pipe.
- Question : EX7 - Solve Example 2.7 for cargo transport rate of 0.0150 through a 0.65 m poly(vinyl chloride) pipeline of length 5000 m. Consider any other data similar to Example 2.7.
