Question

If you use spray-on deodorant, you can find out how fast it comes out of the

can if you know the relative pressure inside the can. Supposing a full can of
deodorant has an exit velocity (V) of 56 feet per second, use the formula
below to find the relative pressure inside the can (p) in psi (pounds per square
inch):
v=8sqrtp
Help me please !

Answer 1

Hey there :)

Lets solve your question,

Given:

Speed = 56 ft/s

To find- Relative Pressure

Solution-

We know that,

`V =8 √(p)`

`= > p = \frac{ {v}^(2) }{64}`

`= > \frac{ {(56)}^(2) }{64}`

`= > 49psi`

Therefore, the answer is 49 psi
