An open tank contains ethylene glycol at 25°c. compute the pressure at a depth of 3.0m.

pressure at depth 3 m is 33.255 kPa

Explanation:

given data

temperature = 25°C

depth = 3 m

to find out

pressure

solution

we know pressure formula that is

pressure = ρ g h   ................1

and we know specific gravity of Ethylene glycol is 1.13

so

1.13 =

ρ (Ethylene glyco) = 1130 Kg/m³

so

pressure will be by equation 1

pressure = 1130 × 9.81 × 3

pressure = 33255.9 Pa

so pressure at depth 3 m is 33.255 kPa

do you have any options?
