Question

Both a gage and a manometer are attached to a gas tank to measure its pressure. if the reading on the pressure gage is 130 kPa, determine the distance between the two fluid levels of the manometer if the fluid is:

(a) mercury with density 13,600 kg/m^3 or
(b) water with density 1000 kg/m^3

Answer 1

a) 0.975 m

b) 13.25 m

Step-by-step explanation:

given data:

pressure gage reading 130 kPa

a) mercury with density 13,600 kg/m^3

let distance between two fluid level is h,

then

we know that
`p = \rho g h`

13600*9.8*h=130*10^3

so h = 0.975 m

b.) water with density 1000 kg/m^3

let distance between two fluid level is h,

then

we know that
`p = \rho g h`

1000*9.8*h= 130*10^3

so h= 13.25 m
