How do the compressible pipe flow formulas behave forsmall pressure drops? Let air at 20°C enter a tube of diameter1 cm and length 3 m. If f = 0.028 with p1 = 102 kPaand p2 = 100 kPa, estimate the mass flow in kg/h for(a) isothermal flow, (b) adiabatic flow, and (c) incompressibleflow at the entrance density.
Air flows through a 6-cm-diameter smooth pipe that has a2-m-long perforated section containing 500 holes (diameter1 mm), as in Fig. . Pressure outside the pipe issea-level standard air. If p1 = 105 kPa and Q1 = 110 m3/h,estimate p2 and Q2, assuming that the holes are approximatedby thin-plate orifices. (Hint: A momentum controlvolume may be very useful.)
Air at 20°C and 1 atm flow at 20 m/s past the flat platein Fig. . A pitot stagnation tube, placed 2 mm fromthe wall, develops a manometer head h = 16 mm of Meriamred oil, SG = 0.827. Use this information to estimatethe downstream position x of the pitot tube. Assumelaminar flow.
