Question

A cylindrical tank with a height of h=1m is filled with water up to
its rim What time is required to empty the tank through an orifice
in its bottom? The cross sectional area of the orifice is (1/400)th
of the tank Find the time required for the same amount of water to
flow out of the tank if the water level in the tank is maintained
constant at a height of h=1m from the orifice

Dear student,H=1maA=1400a= area of orificeA=area of tanktime required to empty the tank=2AHa2gT=2×4002×5=805 secii)  the time required for the same amount of water to flow out of the tank if the water level in the tank is maintained constant at a height of h=1m from the orifice=T2=405 sRegards
