In a carburator of an engine, aire is drawn from atmosphere through section `A` with a velocity of `10m//s`. The narrow section `B` is connected to a petrol tank as shown. The minimum ratio of area of cross section `A` to area of cross section `B`, so that the petrol can just enter the carburator tube is `sqrt(66/x)`. Then the value of `x` is : (density of petrol `=1000kg//m^(3)`, density of air `=2kg//m^(3), g=10m//s^(2)` atmospheric pressure `=10^(5)` Pa and assume density of air remain constant)
