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…
