    Deflating tire, thermodynamics problem

    Oh i see where i made the mistake. After the integration there should be 1 constant on each side to be combined into another constant which is not P(initial). What a silly mistake. From there it is pretty straightforward.

    How Do You Calculate Average Speed If You're Given Distance and Time in Minutes?

    Your average speed is DeltaX/Deltat if you want your speed in km/hour you can convert your units using dimensional analysis. (km/min) * (60min/hour)

    Deflating tire, thermodynamics problem

    Homework Statement Find the size of the hole in the tire after it has taken 60minutes to become flat.Homework Equations Impulse = F*Deltat = DeltaN*Deltap (N=molecules, p=momentum) , P = F/A (A is area of hole), Equipartition for gas in 1-d -> 1/2kT = 1/2mv^2 Derivative of ideal gas law...
