A hypodermic needle is $3\mathrm{.}24$ cm in length and $0\mathrm{.}37$ mm in diameter. What pressure difference between the input and output of the needle is required so that the flow rate of water through it will be $1\frac{g}{s}?($Use $1\mathrm{.}0{10}^{-3}Pa*s$ as the viscosity of water.$)$

$2\mathrm{.}06$cdot$10^5$
