Question

An orifice of area 10sq.mm is made at the bottom of vessel containing water to a height of 10m above the orifice . what is the force on the vessel.​

Answer 1

GIVEN :-

• a = 10× 10^ -6m²

• h = 10m

• g = 10m/s²

• $\rho$ = 1000kg/m³

SOLUTION :-

$\implies$ v = √2gh = √2 ×9.8×10m/s

$\implies$ f = $\rho$ a v²

$\implies$ f = 10³ × 10×10^ -6 × 2×9.8×10

$\implies$ $\huge\red{\boxed{\boxed{f = 1.96N.}}}$

SO ,the force on the vessel is 1.96N.
