Question
Water filled in an empty tank of area 10 A through a tap of cross sectional area A. The speed of water flowing out of tap is given by v (m/s) = 10 
where ′t′ is in seconds.The height of water level from the bottom of the tank at t = 15 second will be :
where ′t′ is in seconds.The height of water level from the bottom of the tank at t = 15 second will be :Options
A.10 m
B.
C.
D.
m
mSolution
Rate of flow = Av
volume of water filled in tank in 15 s
= 10A
= 10 A
height of water level =
volume of water filled in tank in 15 s
= 10A
= 10 Aheight of water level =
