A rectangular tank 0.30m × 0.30m × 0.60 m is filled with ethyl alcohol to a full depth of 0.30 the pressure at the surface of the alcohol is 1.013x10⁶ Pa.

Answer 1

To find the pressure at the bottom of the tank, we need to use the equation for pressure due to a fluid:

P = ρgh

where P is pressure, ρ is density, g is the acceleration due to gravity, and h is the depth of the fluid.

First, we need to find the density of ethyl alcohol. The density of ethyl alcohol is approximately 789 kg/m³.

Next, we can find the pressure at the bottom of the tank:

P = ρgh
P = (789 kg/m³)(9.81 m/s²)(0.30 m)
P = 2317 Pa

Therefore, the pressure at the bottom of the tank is 2317 Pa.
