Solving a problem in physics section 30 point 30 mechan

30. During the time t = 1 hour through the tube diameter d = 40 cm pumped gas mass m = 15 kg. The dynamic viscosity of the gas η = 10-5 Pa ∙ s. If the characteristic size of the diameter of the tube to take, the critical Reynolds number for laminar flow Rekr gas is 2000. Determine the nature of the gas flow.
