Problem

Two identical large tanks,

A

and

B

, are filled with water to the same height

H

. Tank

A

is open to the atmosphere, while Tank

B

is sealed with air at pressure

1.5 P_{\text{atm}}

above the water. Both have identical small holes at the bottom. Without calculating the exact values, determine the ratio of the efflux velocity of

B

A

H = 5\,\text{m}

and

P_{\text{atm}}

corresponds to

10\,\text{m}

of water column.
