Q1) Water discharges from a reservoir A through a 100 mm pipe 15 m long which rises to its highest point at B, 1.5 m above the free suface of the reservoir, and discharges direct to the atmosphere at C, 4 m below the free surface at A. The length of pipe lh from A to B is 5 m and the length of pipe h from B to C is 10 m. Both the entrance and exit of the pipe are sharp and the value of fis 0.08. Calculate (a) the mean velocity of the water leaving the pipe at C and (b) the pressure in the pipe at B. (Ans. v= 1.26 m's, Ps= -28.58 kN/m) Datum level
