For the tank and discharge pipe described in Problem 14.25, with an initial tank depth of 4.5 m, determine the time taken for the difference in depth in the two tanks to fall from 6.0 m to 5.0 m depth if the discharge pipe is connected, at its previous discharge level of 2 m below the base of the first tank, into a second tank, surface area 4.5 m2. The initial depth in the second tank is 0.5 m above the discharge pipe entry and the entry loss coefficient may be assumed to be 1.0.
