Q9 of 17 Page 236

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.

Given,


Height of the tank (h) = 2m


Density of paraffin (d) = 800 kg/m3


g = 10 m/s2


a) The pressure is given by





b) The pressure at depth of 1m




Hence, the pressure at depth of 1m is 8000 Pa.
