A three-blade propeller of a diameter of 1.5 m has a rotational speed is 60 Hz, the activity factor AF is 200 and its static torque coefficient is 0.05. The propeller's integrated lift coefficient is 0.3. a) Calculate the static power and thrust coefficients. b) Calculate the velocity downstream of the propeller and its blade average drag coefficient while the propeller is mounted on a stationary rig.
