Question: Compressible laminar flow, f 64/Re, may occur in capillary tubes. Consider air, at stagnation conditions of 100C and 200 kPa, entering a tube 3 cm

Compressible laminar flow, f ≈ 64/Re, may occur in capillary tubes. Consider air, at stagnation conditions of 100°C and 200 kPa, entering a tube 3 cm long and 0.1 mm in diameter. If the receiver pressure is near vacuum, estimate
(a) The average Reynolds number,
(b) The Mach number at the entrance, and
(c) The mass flow in kg/h.
