Question

An open tank contains brine to a depth of 2.2 m and a 4.3 m layer of oil on top of the brine. The density of brine is 1,030 kg/m³ and the density of oil is 880 kg/m³.
The gage pressure (kPa) at the bottom of the tank is most nearly _____.

Answer 1

Answer:

gauge pressure at the bottom = 59.35 kPa

Explanation:

given data

brine depth 1 = 2.2 m

oil depth 2 = 4.3 m

density of brine = 1,030 kg/m³

density of oil = 880 kg/m³

solution

we get here gauge pressure at the bottom of the tank that is

gauge pressure at the bottom = density of brine × g × height   + density of oil × g × height   ..............................1

put here value and we get

gauge pressure at the bottom = 1,030 × 9.81 ×2.2 + 880 ×9.81 ×4.3

gauge pressure at the bottom = 59350.5  N/m²

gauge pressure at the bottom = 59.35 kPa
