Glycerin of density \( 1.25 \times 10^{3}\,\text{kg}\,\text{m}^{-3} \) is flowing through the conical section of pipe. The area of cross-section of the pipe at its ends are \( 10\,\text{cm}^{2} \) and \( 5\,\text{cm}^{2} \) and pressure drop across its length is \( 3\,\text{N}\,\text{m}^{-2} \). The rate of flow of glycerin through the pipe is \( x \times 10^{-5}\,\text{m}^{3}\,\text{s}^{-1} \). The value of \( x \) is ______.
