Question

We know that pressure can also be calculated by using the formula p=hdg
A rectangular storage tank is filled with paraffin. The height of the tank is
2m. Density of paraffin is 800 kg/m3
, the value of g is 10 m/s2
Calculate
a) the pressure at the bottom of the tank
b) the pressure at a depth of 1 m.

Answer 1

a) 800×2×10 = 16000 kg/msec

b) 800×10×1 = 8000kg/msec

hope this helps. :)

Answer 2

a)
P = hdg
= 2 × 800 × 10
= 16000 Pa
= 16 kPa
Pressure at bottom of tank is 16 kPa

b)
P = hdg
= 1 × 800 × 10
= 8000 Pa
= 8 kPa
Pressure at the depth of 1 m is 8 kPa
