$($a$)$ In inclined manometer is connected to pipe in which water is flowing. The manometer fluid is mercury $($density $=13.$ and the deflection in the inclined tuse $k\frac{g}{n}$ o is $250$ mm with an inclination angle of $30.$ Calallate the preassure difference between the two points in the pife.

$($b$)$ Estimate the uncettainty in the preasure measuremonts if the uncertaing in deflection measurenents is $11$ mm and uncertainty in the angle measurements is $t+-1C$

$($c$)$ In a practical scenario, how woud an indlined manameler bo more benfincial then a U$-$Euse manometer for meaquring Low preassure differences.
