2. In the tire of a car with a volume of 30 lt (0.03 m3) you create a hole with a diameter of 0.5 m. If the pressure in the tire was initially 2 bar and the temperature is 298K, how much time will be added so that the pressure drops to 1 bar? Given that: Air follows perfect gases equation. The rate of diffusion of a gas from one of is given by the relation: ΔΝ/Δt=pANa/2πMRT)^1/, where N is the number of particles escaping, T time, p the pressure of , Na Avogadro number, M is the molecular weight (air 29*10-3 kg mol ), R constant.
