$9\mathrm{.}4\mathrm{.}9.$ Determine the discharge $($in $\frac{m^3}{s})$ through a $6-$ft Parshall flume if the gauge reading $H_a$ is $0\mathrm{.}701$ m and $H_b$ is $0\mathrm{.}579$ m $.$

$9\mathrm{.}2\mathrm{.}3.$ The center line velocity in a $4-$in$.-$diameter pipe is $24\mathrm{.}4f\frac{t}{s}$ based on Pitot tube readings. Determine the reading on the Pitot tube scale $h$ in Figure $9\mathrm{.}4$b$)$ if the pipe fluid is water and the manometer fluid is mercury $(SG=13\mathrm{.}6.$Estimate the discharge. Why is it an estimate?

THE CORRECT ANSWER IS delta h $=0\mathrm{.}734$ ft $,$ Q$=2\mathrm{.}13$ cfs
