A rectangular box is completely filled with a liquid of density `rho`, as shown in Fig. The box is accelerated horizontally with a constant acceleration a. Determine the gauge pressures at the four points `A, B, C` and `D`.

Text Solution

Verified by Experts

At point `A, P_(A)=0`
At point `B, P_(B)=P_(A)+rhogh=rhogh`
At point `C, P_(C)=P_(B)+rhoaL=rhogh+rhogL`
At point `D, P_(D)=P_(C)-rhogh=rhoaL`
Or alternatively, `P_(D)=P_(A)+rhoaL=rhoaL`
