    Equation Sheet:

    $$ 0 = \frac{ d}{dt} \int_{cv} \rho d V\llap{-} + \int_{cs} \rho ( \boldsymbol {V}\cdot d \boldsymbol{A} ) \tag{mass}$$

    $$ \sum \boldsymbol{F} = \frac{ d}{dt} \int_{cv} \rho \boldsymbol{v} d V\llap{-} + \int_{cs} \boldsymbol{v}\rho ( \boldsymbol {V}\cdot d \boldsymbol{A} ) \tag{Momentum}$$

    $$ \dot Q - \dot W_s = \frac{d}{dt} \int_{cv} \rho \left( \frac{V^2}{2} + gz + u \right) d V\llap{-} + \int_{cs} \left( \frac{V^2}{2} + gz + u + \frac{p}{\rho} \right) \rho \boldsymbol {V}\cdot d \boldsymbol{A} \tag{Energy}$$

    Hi @erobz -- do you still need this? It's probably better to store such LaTeX helper sheets locally on your computer.

    Hello sir. I have a question for you. I'm Alex, a guy here with autism.

    But you have mech. engineering as a degree? So, do you do engineering and stuff?

    I did for a while, but currently no.

    That is alright. What did you do specifically with engineering? Did you design appliances, aerospace, actuators or cars or something else? Engineering is fascinating in my opinion, and it would be cool to become one in the future.

    Hi, would you mind if I share my experimental data here?
    Thanks

    Hello, it’s probably better to “start a conversation” as opposed to posting it here though. I’ll get that going.
