Question

What is the pressure at the bottom of a 25 ft volume of hydraulic fluid with a weight density of 55 lb/ft3 a. 114.6 psi b. 1375psi c. 2.2 psf. d. 9.55 psi e.1395 psf

Answer 1

d) 9.55 psi

Step-by-step explanation:

pressure at the bottom is =ρgh

weight density is ρg=55 lb/ft³

h=25ft

pressure at the bottom is =
`55* 25`

=1375psf

1 ft = 12 inch

pressure at bottom =
`(1375)/(12^2)`

= 9.55 psi

so, answer will be option (d) which is 9.55 psi
