Question 1 of 30

Time left: 00:00

A sealed tank contains a liquid of density \(920\,\text{kg m}^{-3}\). A pressure gauge is located at a point \(1.50\,\text{m}\) below the free surface. The free surface is at atmospheric pressure. What gauge pressure should the instrument read at the gauge position? Take \(g=9.81\,\text{m s}^{-2}\).

Select one option.

\(6.77\times 10^{3}\,\text{Pa}\)
\(9.81\times 10^{3}\,\text{Pa}\)
\(1.20\times 10^{4}\,\text{Pa}\)
\(1.35\times 10^{4}\,\text{Pa}\)
\(1.50\times 10^{3}\,\text{Pa}\)
