Question

Water flows from a tank through a pipe section as shown below. Points 1 and 2 are located at the same vertical height and the pressure gauges are mounted at the same vertical position. If the water velocity at point 1 is negligible, frictional losses are essentially zero, and there are no entrance/exit effects in the tank and pipe, how is the pressure at points 1 and 2 related?
