Also, pretty sure your final equation for DKE+DPE does not equal 28.95

[@maxwellcunningham8908]

Yea I cant get that value either. Even the equation on screen does not equal 28.95, i get 67.04

[@LessBoringLectures]

CORRECTION: At 2:53, in the orange line, d1 is shown as substituted with 0.06 and d2 is shown as substituted with 0.08. It should be the opposite. However, the final answers are still correct: W_net output is indeed still 28.95531...kW

At 1:22 why do we scratch Wout? Isn't W out essentially the W oil? Can someone please help?

[@avielb]

because the work is done on the oil, giving it kinetic and potential energy. the oil in itself does not do work.

[@diyaazaghloul756]

Amazing video thank you

[@johnwagner5218]

At 2:53, when you substitute in diameters, you write d1 and d2 in the v2 and v1 spots respectively. Is this intentional or a mistake?
