2. A propeller on a gas turbine rotates 64° every 2.70 minutes. What is the angular velocity in rev/s? What is the linear speed of a point at the tip of the blade if the diameter of the blade is 5.37 ft?

  • Math -

    a. 64o/2.70min * 1rev/360o * 1min/60s=
    = 1.1 rev/s.

    b. C = pi*D = 3.14*5.37=16.9 Ft=5,12 m.
    The Circumference.

    b. 64o/2.70min * 1rev/360o * 5.12m/rev
    * 1min/60s = 5.62 m/s.
