A 20 cm × 10 cm venturimeter (Cd = 0.96) carries water. A differential mercury water manometer shows a reading of 10 cm. (i) Calculate the discharge. (ii) If the loss of head in the expansion part of the meter is taken as eight times the velocity head in the pipe, calculate the total head loss due to the ventur imeter.
