a tunnel was constructed with a very large pipe with a cross-sectional area of 1.5m^2. it is at a given height descending to 5m^2 and then narrows to 0.500m^2, where it terminates in a valve. if the pressure at point 2 is the atmospheric pressure and the valve is opened wide wat3er allowed to flow freely, find the speed of the water leaving the pipe.
