Current Attempt in Progress

A Venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at speed $v_2$ through a horizontal section of pipe whose cross$-$sectional area is $A_2=0\mathrm{.}0841m^2.$ The gas has a density of $=1\mathrm{.}30k\frac{g}{m^3}.$ The Venturi meter has a cross$-$sectional area of $A_1=0\mathrm{.}0341m^2$ and has been substituted for a section of the larger pipe. The pressure difference between the two sections is $P_2-P_1=170Pa.$ Find $($a$)$ the speed $v_2$ of the gas in the larger original pipe and $($b$)$ the volume flow rate $Q$ of the gas.
