Question 16 4 pts A 1.1m diameter propeller is installed on a plane to generate thrust. The mass flow rate of air through the propeller is 145 kg/s. The density of the air is 1.28 kg/m3, and the flow is incompressible. If the diameter of the slipstream far upstream of the propeller is 1.22 m, how fast is the plane traveling? Enter your answer in m/s to at least three significant figures.

Question 30 6 points Save Answer (LO4) A wind turbine with a 40-m-diameter rotor is rotating at 21 rpm under steady winds at an average velocity of 14.7 m/s. The electrical power output from the generator is 350 kW. The efficiency of the gearbox is 93% and generator efficiency is 86%. Take the density of air to be 1.013 kg/m. Answer the following questions; use the white paper to work-out your calculations and then choose the correct answer from the...

10 pts D Question 4 A steel shaft, d-150 mm in diameter and L-2.47 m long, transmits a constant torque of 389 N-m at 3914 rpm. Assume that the machine it is driving has no rotational inertia, and determine how long it would take the shaft to coast to a stop il its input power were removed. The steel weighs 0.00783 kg/cm 3. The mass of the shaft can be calculated from m-3.14 L d 2 and mass moment of...
