Properties Of Solids And Liquids Question 216

Question: There is a hole in the bottom of tank having water. If total pressure at bottom is 3 atm (1 atm = 105N/m2) then the velocity of water flowing from hole is[CPMT 2002]

Options:

A)400m/s

B)600m/s

C)60m/s

D)None of these

Show Answer

Answer:

Correct Answer: A

Solution:

Pressure at the bottom of tank P=hρg=3×105Nm2

Pressure due to liquid column Pl= 3×1051×105=2×105

and velocity of water v=2gh

 v=2Plρ=2×2×105103=400m/s
