A 150mm * 75 mm venturi meter with a coefficient of discharge 0.98 is to be replaced by an orifice meter having a coefficient of discharge 0.6. If both the meters are to give the same differential mercury manometer reading for a discharge of 100 litres per second and the inlet diameter is to remain 150 mm, what should be the diameter of the orifice.
