Plastic cups in love – experimental demonstration of Bernoulli’s principle

Plastic cups in love What does a flying airplane and a pitcher's curve ball have in common. Well, besides the fact that both travel through the air at amazingly fast speeds - both are based on a principle called Bernoulli's principle. Bernoulli, (pronounced Burr New Lee) was a Swiss mathematician who liked to piddle around with these types of things. Now we get to piddle Out of the string, make 2-1 foot long pieces. Using tape, attach one end of the string to the bottom of one of the cups. Take the other end of the string and attach it to a table. Repeat steps 2 and 3 with the second cup. When taping this string to the table, make sure that the cups will…

Pressure

Can we please lower the pressure in here?

Can we please lower the pressure in here? Named after Daniel Bernoulli, the Bernoulli Principle states that as the velocity of a fluid increases, a decrease in pressure occurs. The mathematician Daniel discovered many new ideas regarding fluids and pressure. For instance, Bernoulli, who had earlier begun to study medicine, wanted to know about the relationship between the rate of blood flow and its pressure. He poked a hole in a pipe and stuck a straw in it and noticed that when the fluid sped up, the liquid rose higher in the straw. Soon doctors all over Europe were poking holes in patient’s arms and sticking little glass tubes in them to test their blood pressure. Ouch! This practice continued for nearly 200 years until…
