Question

6. A vessel of base area 100 cm x 60 cm and height
200 cm is completely filled with a liquid of density
1.1 x 103 kg m?
(a) Ignoring the atmospheric pressure, find :
(i) the thrust at the bottom of the vessel​

Answer 1

Answer:

Given that,

density of water (ρ)=103 Kg/m3

water fixed up till height (h)=2 m

Area of base (A)=100 m2.

assuming atmospheric pressure (P0)=1 atm≃105 Pa

so, pressure at bottom of tank,

P=P0+ρgh.

    =105+103×10×2[g=10 m/s2]

P=(1.2×105) Pa

Thus, thrust on bottom surface,

F=P.A=(1.2×105)×102⇒F=1.2×107 N
