Question

Find the total pressure ‘A’ at the bottom of the jar, 50 cm in height. The mass of the liquid is 4300 kg and the volume is 0.055 m³. The atmospheric pressure on Earth is 101.3 kPa.      

Answer 1

density of liquid$=\frac{mass}{volume}=\frac{4300kg}{0.055m^3}=78181.82kg/m^3$

pressure due to liquid$=density\times gravity\times height=78181.82\times 9.8\times 50/100=383090.918Pa$

total pressure at the bottom$=383090.918+101,300=484,390.918Pa$
