If a dust-proofing oil at 30°C had been flowing at 0.046 m /s through a 150-mm pipe in which along-radius flow nozzle 75 mm in diameter, what would have been the deflection of the mercury? Assume C=0.98.
Given a 60-meter tall wind turbine tower and is capable of withstanding shear wind up to 20m//s. The maximum deflection of the top of the tower is 1.25% the total tower height in order to avoid the turbine clades striking the tower. Consider standard factors of safety.
Make any assumptions with values to find the pressure, power, and safety factor.
