Ok, I agree, but the angle of the dot product here is the angle between the control surface normal vector and the flow vector. We should either not call this variable ##\theta## as this is the lid angle (lets say this is ##\alpha##), or we take our area with the assumption that all the outgoing...
Hi erobz,
Sorry for the delay. This is my first time really using LaTeX and it has been pretty painful starting off.
As promised, below is my original hand calc that I scanned, but correctly put in LaTeX now:
Scenario 1 in my first post was when the lid is closed, and the Bernoulli Principle...
Hi erobz,
I understand that Bernoulli is conservation of energy while RTT is conservation of momentum, but I am not sure how I can use these at the same time to come up with an equation for the force on the lid.
Addressing your questions:
1: Realistically, this area would be something of an...
Hi,
I am trying to map out the forces that act on a raincap installed at the end of a pipe, but I have ran into a problem where I am getting 2 different equations depending on the method that I use. I'm definitely missing something here and I was hoping someone is about to point it out to me...
