Triangular notch with vertical angle of 90° measures a flow rate. If the value of Cd = 0.6 and there was an error of 2.5 mm in the measurement the head, then calculate the percentage error in estimation of discharge of 21 lit/s.

Water flow through a venturi meter an inlet dia. = 100 mm and throat dia. =50 mm , P at inlet = 70 kpa. And at the throat 75 mm mercury, if the discharge coefficient = 0.95 , find the flow? %3D

600mm water diameter 300mm 1. diameter 02 150mm Mercury (SG = 13.6) A venturi meter with diameter of 300mm is attached to a 600mm main pipe and has its axis inclined downward as shown. a) Discharge if head loss is neglected is Blank 1 cu.m./s b) Discharge if head loss is 500mm from point 1 to 2 is Blank 2 cu.m./s c) Coefficient of discharge is Blank 3 The manometer shows a deflection of 15cm of mercury (SG =13.6). If the flowing fluid is water and direction is from 1 to 2, determine the
