A 6 cm diameter pipe with water flowing at a discharge of 1/min. At a section, the pipe has a sudden expansion to a size of 9 cm in diameter. If the pressure just upstream of the expansion is 20 kN/m2, then calculate the pressure (in kPa) just after the expansion. Assume the pipe to be horizontal at the expansion region.
