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 72 feet per second, use the formula below to find the relative pressure inside the can (p) in psi (pound square inch)


`v = 9 √(p)`

Answer 1

64psi is the answer for Apex!

Explanation:

Answer 2

we have that
v=9√p-----> squaring both sides-----> v²=9²(√p)²
p=v²/81
v=72 ft/sec
substitute the value of v in the formula
p=(72)²/81------> p=64 psi

the answer is 64 psi
