QUESTION NO--01

(a) For A Town with population of of 200000 a water supply scheme is to be designed.The maximum daily demand may be assumed as 200 litre per capita per daY. The storage Reservoir is situated 5 kilometre away from the town. Assuming loss of head from source to town as 10m and coefficient of friction for the pipe material as 0.012, recommend the size of supply main. 50% of the daily demand has to be pumped in 8 hours for the purposed scheme.

Solution:-
 Maximum Daily Water Demand = 200 LPCD 
Maximum Water Demand = 200000 x 200 = 40 MLD 
Maximum Water Demand for which supply main is to be designed = 50% of daily demand 

Q = (50 / 100) x 40 x 106
 Liters per 8 hours 

Q = (50 / 100) x (40 x 106) / (8 x 60 x 60) 
Q = 0.694 m3/s
 L = 5000 m HL
 = 10 m f = 0.048 
HL
 = (f * L*v2) / (2gd) 
10 = (0.048 x 5000 x v2) / (2 x 9.81 x d) 
v = ( Q / (∏ /4)) x d2 v = ( 0.694 / (3.14/4)) x d2
 v = 0.884 d2 
10 = (0.048 x 5000 x (0.884 d2)2) / (2 x 9.81 x d) 


d = 0.955 m
