All of students solved the continuity equation well so, they found 𝑉1 and 𝑉2 correctly
Many students missed the pressure force term which is acting on the flange bolt
Some of students could not derive the momentum equation correctly so they put wrong sign for the term of 𝑚̇2𝑉2
One student made a calculation mistake when he calculate 𝑄
