c) A system is equipped with two pressure gages and a manometer, as shown below. For Ah=8 cm, determine the pressure difference AP=P2-P Manometer fluid SG 2.67 Air Ah Water 15C d) The pressure of water flowing through a pipe is measured by the arrangement shown below. For the values given, calculate the pressure in the pipe. Po - 30 kPa h-50 cm Air Gage fluid SG 2.4 Oil SG=0.87 L-6 cm Pipe Water 15 C h-8 cm 2-6 cm
