Problem

A swimming pool is filled with engine oil of density

820\,\text{kg}\,\text{m}^{-3}

to a depth of

2.5\,\text{m}

. Calculate the absolute pressure at the bottom of the pool. Take atmospheric pressure

p_0 = 1.01 \times 10^{5}\,\text{Pa}

and

g = 9.8\,\text{m}\,\text{s}^{-2}

. a)

1.42 \times 10^{5}\,\text{Pa}

2.01 \times 10^{4}\,\text{Pa}

1.21 \times 10^{5}\,\text{Pa}

1.26 \times 10^{5}\,\text{Pa}
