A horizontal pipe carries a smoothly flowing fiquid or density

of $1390k\frac{g}{m^3}.$ At Locations $1$ and $2$ along the pipe, the diameters are $d_1=6\mathrm{.}17cm$ and $d_2=2\mathrm{.}31cm,$ respectively.

Is the flow speed at Location $2$ higher or lower than the flow speed at Location $1?$

higher

lower

cannot tell from the data

The flow speed at Location $1$ is $2\mathrm{.}53\frac{m}{s}.$ What is the pressure difference $P$ between Location $2$ and Location $1($including its sign$)?$ Ignore viscosity.
