mass of oil=density*volume=.90g/ml*18m^3
= .90kg/m^3\ * 18m^3
Weight of oil= above massoil* 9.8N/kg
= .90kg/m^3\ * 18m^3
Weight of oil= above massoil* 9.8N/kg
Answer
Given:
OIl
Sp G= 0.9
Dimension
3m x 3m and H= 2 m P=2mx 900kg/m^3 x 9.8m/sec^2
F= P x A P = 1800kg/m^3 x 9.8 m/sec^2
but: kg-m/sec^2 is Newton
P=Hdg P =17640 N/m^2
Area= Assume rectangular Tank P=17640 N/m^2 x9m^2
Area= 3x 3= 9^2 P=17640 x 9
F = 158760 N then divide by 9.8 = 16200 kg
