Most students approached correctly to solve the problem
One student could not solve the problem well and he couldn’t find the 𝜋0, 𝜋1, 𝜋2
One student made a mistake when he derived the 𝜋2 which should be the form of Reynolds number
Some of students could not answer for the pressure changing when the velocity is doubled
