The pressure at the bottom of the tank is given as 13,992 pa. See the explanation below.
The formula for atmospheric pressure is given as:
P = Hβg where:
β is the density of the bunker fuel = 755kg/m³
h is the height of the storage tank and;
g is 0.92m/s
P = 20 * 755 * 0.92
= 13,892
Hence, the pressure at the bottom of the tank is: 13, 992 pa
