Question

Calculate the liquid pressure at A,B,C
= {Take g} = 10ms²
= {Take d} = 1000 kg/m³

explain step by step. ​

Answer 1

Pressure = Hdg

H ===> Height

d ===> Density

g ===> Acceleration due to gravity

On A:

Height = 60 cm

90/100m = 0.6m

Pressure = 0.6m x 10ms^-2 x 1000 kg/m^3

Pressure = 6000 Pascal

On B:

Height = 30 cm = 0.3m

Pressure = 10 x 0.3 x 1000 = 3000 Pascal

On C:

Height = 0 cm

0 cm = 0m

0m x 10m/s^2 x 1000 kg/m^3 = 0 Pascal

HAVE A NICE DAY!!!

HOPE IT HELPS YOU!!!
