B) A water tank with vertical sides is 3m wide and contains water with a density of 800 kg/ m3 to a depth of 1.8m. Calculate the hydrostatic thrust on the side of the tank. ?

1 Answer

#F=\rho gBL\barx#

Explanation:

HINT: The hydro static force #F# on a vertical rectangular plane, submerged in a liquid of density #\rho#, having vertical length #L# & width #B# is given by the following formula

#F=\rho gBL\barx#

Where, #\bar x# is the vertical depth of centroid of plane from free surface of liquid
