he pressure drop in a Venturi meter varies only with fluid density, relocity of approach and the diameter ratio of the meter. Venturi neter 1 in water at 20°C shows a 7-kPa drop when approach velocity $ 5 m/s. Meter 2, geometrically similar to 1, is used in a 1/6 m/s flow of benzene (density = 680 kg/m). Find the upstream diameter that vill yield a 18-kPa drop in meter 2?

Question
The pressure drop in a Venturi meter varies only with fluid density,
velocity of approach and the diameter ratio of the meter. Venturi
meter 1 in water at 20°C shows a 7-kPa drop when approach velocity
is 5 m/s. Meter 2, geometrically similar to 1, is used in a 1/6 m3/s flow
of benzene (density = 680 kg/m). Find the upstream diameter that
will yield a 18-kPa drop in meter 2?
O 148 mm
O 144 mm
O 146 mm
O 142 mm
None of these
