Hello everyone, I have a few questions. I'd like to compare the efficiency of transport ships under sail. I've found a formula for calculating thrust F: F = 1/2*p*A*C_L*V^2 C_L is the lift coefficient, but how do I find this out? And can I even use this formula, given that different sails are constructed differently….
Hello dear community, I just can't find the right solution to a physics problem. The solution to this problem would actually be 12 minutes, but I would like to know the solution. A fountain consists of two basins. The first basin empties into the second through an opening A with a cross-section S. A pump…
Hello? I have a question: How do you calculate the flow rates for parallel pipes? I'm really stuck and would appreciate any suggestions.
I need to calculate the time it takes for the object to reach the ground and its terminal velocity, but I've never been so confused. I'd appreciate some help. I've been trying to figure it out for hours, but I missed a lesson and now I'm behind 🥲. the topic is air resistance.. Spherical object…
For the physics experts: Imagine a large container of water under constant pressure. The container has several holes of different diameters at different locations. Which hole will the water spray the farthest from? I regularly find the Bernoulli equation with variable pressure on this topic, but not this situation. What would be your answer to…
Hello, I wanted to ask if the movement of an air bubble in a glass tube is uniform at a steep/large incline? And at a slight incline, it wouldn't be uniform, right? Thank you!
Good morning, Sure, the curvature and shape of the wing do that, but how does the curvature affect the airflow so that the air at the top is faster? Thanks for the answers
How do you calculate this? A few sources would also be helpful.
https://www.eputec.de/das-wickelrohr-verstand-so-funktioniert-die-kuehlung-bis-46-c/ Who knows about this technology and enjoys tinkering? If you have 1000 to 10000 If vortex tubes are cleverly connected next to and behind each other, can very hot air be produced with such a machine?
Hello, as I already mentioned in the question, this is about the Bernoulli equation in physics. The equation itself is understandable, but the rearrangements sometimes aren't. Here's an example: A large, open-topped water tank has a small hole on one side at a height ∆h below the water surface. At what speed does the water…
Hey, I'm stuck on the following problem. I've tried applying the continuity condition and the Bernoulli equation, but when I solve it, v2 always disappears.
How do you get from 2 to the last step? I have already solved the binomial formula, but I always get a different result.
