A cylindrical vessel contains a liquid of density ρ upto a height h. The liquidized by a piston of mass m and area of cross-section A. There is a small hole at the bottom of the vessel. The speed v with which the liquid comes out of the hole is –
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Applying Bernoulli’s theorem at 1 and 2 : difference in pressure energy between 1 and 2 =
difference in kinetic energy between 1 and 2
or ρ gh + 
=
ρ v 2
or v = 
=
