A tank is 10 m long, 8 m wide, 4 m high, and contains kerosene with density 820 kg/m3 to a depth of 3.5 m. (Use 9.8 m/s2 for the acceleration due to gravity.) (a) Find the hydrostatic pressure on the bottom of the tank.

28,126pascal

Explanation:

Hydrostatic pressure exerted on the bottom of the tank can be calculated using the formula

P = hpg where;

h is the depth of the tank = 3.5m

p is the density of the kerosene = 820kg/m³

g is the acceleration due to gravity = 9.8m/s²

Substituting the values into the formula we have;

P = 3.5*820*9.8

P = 28,126Pascal
