A very powerful vacuum cleaner has a hose 2.75 cm in diameter. With no nozzle on the hose, what is the weight of the heaviest brick that the cleaner can lift?(adsbygoogle = window.adsbygoogle || []).push({});

So I need to find the pressure and then multiply by the area of the hose... but if P= density*g*h... would I use the density for air? What would the height be?

Am I approaching this the right way?
