A pitot-static tube measures the total pressure pr and the local pressure p in a uniform flow in a 4-cm- diameter water pipe. Calculate the flow rate if: (a) Pr= 1500 mm of mercury and p = 150 kPa (b) PT = 250 kPa and p = 800 mm of mercury (c) Pr=900 mm of mercury and p = 110 kPa (d) Pr= 10 in. of water and p = 30 lb/ft² (-0.6) 0(0)
