A liquid $(=1\mathrm{.}65\frac{g}{c}{m}^3)$ flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross$-$sectional area is $10\mathrm{.}0c{m}^2,$ the flow speed is $257c\frac{m}{s},$ and the pressure is $1\mathrm{.}20{10}^{5}Pa.$ In the second section, the cross$-$sectional area is $4\mathrm{.}00c{m}^2.$

$($i$)$

$($a$)$ Calculate the smaller section$\text{'}$s flow speed. $($Enter your answer to at least two decimal places.$)$

$\frac{m}{s}$

$($b$)$ Calculate the smaller section$\text{'}$s pressure.

Your response differs from the correct answer by more than $10\%.$ Double check your calculations. Pa
