From a flow-net diagram drawn under a concrete dam, following information are obtained:

(i) The head difference between upstream and downstream side of the dam is 9 m .

(ii) The total number of equipotential drops between upstream and downstream side of the dam is 10 .

(iii) The length of the field nearest to the toe of the dam in the downstream side is 1 m .

If the soil below the dam is having a saturated unit weight of $21 \mathrm{kN} / \mathrm{m}^3$ and unit weight of water is $9.81 \mathrm{kN} / \mathrm{m}^3$, then the factor of safety against the quick condition will be __________ (round off to two decimal places).
