Question
(a) State and prove Euler's equation of motion. Obtain Bernoulli's equation from Euler's equation.
(b) A horizontal venturimeter is provided in a $250\text{ mm}$ diameter pipe line conveying water. The throat diameter of the venturimeter is $25\text{ mm}$. If the pressure in the pipe is $147.15\text{ kPa}$ and the vacuum pressure at the throat is $280\text{ mm}$ of mercury, calculate the rate of flow in the pipe. Assume $Cd = 0.98$.
(c) A pitot static tube is mounted on an aircraft travelling at a speed $300\text{ kmph}$ against a wind velocity of $20\text{ kmph}$. If the specific weight of air is $12\text{ N/m}^3$, determine the pressure difference the instrument will register. Take $Cv = 0.98$.
