The length of pipe h from A to B is 5 m andthe length of pipe h from B to C is 10 m. Both the entrance and exit of the pipe are sharp andthe 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/m²)Datum level
