Ans) Apply Bernoulli equation between point 1 and 2 located at pump inlet and pipe exit respectively           P1 /  + V12/2g + Z1 = P2 /  + V22/2g + Z2 + Hm       Hm is Head supplied to pump        According to question, Q = 500 L/s or 0.5 m3/s     => V1 = Q / A1 = 0.5 / [(/4)(0.6)2] = 1.77 m/s     => V2 = Q / A2 = 0.5 / [(/4)(0.9)2] ...
