A cubical box 20 cm on a side is completely immersed in a fluid. At the top of the box the pressure is 105 k Pa and at the bottom the pressure is 106.8 Pa. What is the density of the fluid ? Guess the fluid.

Text Solution

Verified by Experts

As `P_(bottom)=P_(top)+rhogh`,`rho=(P_(bottom)-P_(top))/(gh)`,`rho=((1.069xx10^5Pa)-(1.059xx10^5Pa))/((9.81(m)/(s^2))(0.2m))=920(kg)/(m^3)`
The fluid in question may be olive oil.
