Comments

• 68.29% of students did not consider the correct flow rate when computing the velocity.

The inlet flow rate Q was given, therefore, since there are two outlets with equal section area, the exit velocity is V = (Q/2)/A.

• 73.17% of students used the wrong mass flow rate in applying the angular momentum equation. As for the exit velocity, the outlet mass flow rate is 𝑚𝑚̇𝑜𝑜𝑜𝑜𝑜𝑜 =𝜌𝜌𝜌𝜌/2.

• 97.56% of students did not solve the angular momentum equation including the relative motion term (-Rω) in order to determine the rotation rate if there is no retarding torque.

• 60.97% made mistakes in using V = Rω.
