WOW! Someone who speaks English, doing engineering videos on Youtube! And it's clear and correct too!

In the change in pressure how come it is being multiplied by 10^3?

We were given enough information to calculate a mass flow rate. So aside from not being given mass, how else would we know that the force of gravity can be neglected?? I'm very confused, because if I calculate the force due to gravity, it's equal to the reaction force in the y direction, and would completely cancel out. I'm missing something fundamental here...any help would be appreciated!

thank you very much for these great videos

Could you please provide me with the textbook or the reference from which you bring these problems?

[fadhillizardo]

how do you know the direction of vector dA?

[lazer]

How would you know if there is a body force?

velocity at 2 was 4i why u have used 16 in the calculation of Ry

You forgot about the external Pressure Forces acting on the elbow since your pressures are in absolute
