Does an eductor work on the Bernoulli equation?

AI Thread Summary
The Bernoulli equation applies only along a streamline, which raises questions about its relevance to eductors. Eductors utilize the Bernoulli effect from pumped water to create suction, drawing water and sediment from an excavation site. The design of the tube used in eductors can vary in material, such as steel or plastic, and its diameter is influenced by pump power and the nature of the work. Understanding the relationship between eductors and the Bernoulli equation is crucial for effective application in fluid dynamics. The discussion highlights the practical implications of this relationship in engineering contexts.

What i know is that the Bernoulli equation is applied only along a streamline. Is it correct to say that eductors work on the Bernoulli equation?

The Bernoulli effect from the flow of pumped water causes suction at the mouth of the dredge. Water and sediment are sucked from the excavation site and released from the far end of the tube. The tube can be made of any rigid material such as steel or plastic. The diameter of the tube depends on the power available from the pump and whether delicate work is required.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
