Question

A pressure gage connected to a tank reads 60 psi at a location where the barometric reading is 29.1 in Hg. Determine the absolute pressure in the tank. Take rhoHg = 848.4 lbm/ft3.

Answer 1

Answer:513 psi step by step in explanation

Step-by-step explanation:

First We need to convert the inches to ft using a conversion factor then:

1 in= 0.083ft , so 29.1 in=2.42ft

We use the equation of fluids that is:

P= P, +ρgh

We need to include the conversion of psf to psi

1 psf=0.0069 psi

P= P, +(ρgh*0.0069)

P=60 psi + 848.4
`(lbm)/(ftx^(3) )` * 32
`(ft)/(s^(2) )`*2.42ft*0.0069

P=513psi
