points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

Rats have up to 70 whiskers on their faces, varying hugely in size and shape. Almost every mammal possesses whiskers, but these rodents are what we call “whisker specialists”, meaning they have ...

For a 'street science' experiment I approached holidaymakers with a ping-pong ball and a funnel, to show them a classic and counterintuitive science demonstration. It involves something known as ...

Bernoulli's equation is a simple but incredibly important equation in physics and engineering that can help us understand a lot about the flow of fluids in the world around us. It essentially ...
