Water flows steadily from an open tank into a pipe as shown in the figure. The elevation of the top of the tank is 12.3 m, and the elevation at the pipe is 3.80 m. The initial cross-sectional area of the pipe (at point 2) is 5.60×10−2 m^2; and at where the water is discharged from the pipe (at point 3), it is 1.40×10−2 m^2. The cross-sectional area of the tank is very large compared with the cross-sectional area of the pipe.

Q: Assuming that Bernoulli's equation applies, compute the volume of water DeltaV that flows across the exit of the pipe in the time interval 4.40 s.

the pipe has a cross sesctional are of 1.6cm^2.

The water comes out of the pipe at a speed of 14cm/s.

How long does it take to fill the tank? Give your answer in hours and minutes, correct to the nearest min
