A4.0-mm-diameter hole is 1.0 m below the surface of a 2.0-m-diameter tank of water. what is the rate, in mm/min, at which the water level will initially drop if the water is not replenished? express your answer to two significant figures and include the appropriate units.

mm/min

Explanation:

h = height of the water level above the hole = 1 m

= diameter of hole = 4 mm = 0.004 m

= Area of cross-section of hole =

= diameter of tank = 2 m

= Area of cross-section of tank =

R = rate at which the water level drop

Rate at which the water level drop is given as

m/s

mm/sec

mm/min

mm/min
