Question

A closed rectangular tank 10 m long, 5 m, wide and 3 m deep is completely filled with and oil of specific gravity `0.92` . Find the preesure difference betweenn the nrear and front cornrers of the tank, if is moving with an acceleration of `3 m//s^(2)` in the horizontal direction
A. `27.6 kPa`
B. `50 kPa`
C. `60 kPa`
D. `70 kPa`

Answer 1

(a)We consider a fluid body of cross-sectional area A (shown in fgure)

`p_(1)A-p_(2)A=ma`
or `(p_(1)-p_(2))A=rhoAla`
or `r_(1)-P_(2)=rhola`
`=0.92xx10xx3`
`=27.6 kPa`
