Formula

$1$ point

For the pipe flow reducing section of the figure below, $D1=10\mathrm{.}0m,D2=5\mathrm{.}96m,$ and $P2=101325Pa.$ If the manometer reading is $95\mathrm{.}0$ cm $,$ what is the pressure at P $1$ in Pa $?$ Assume the fluid flowing from $1$ to $2$ is water, and assume the fluid in the manometer is mercury.
