... I call it "Wardrobe Malfunction", because you'd think this sort of thing would have been guarded against.

I think it would effectively increase the pressure differential, massively.

If we assume that an object entering the wardrobe in our frame of reference, at our rate of time, and exits in much faster Narnia time at the same velocity relative to Narnia time then, related back to Earth, they must have been accelerated. If we assume that time in Narnia is ten times faster than Earth time, then in order to have the same velocity in Narnia time, the water must be accelerated to ten times its velocity on Earth, related back to Earth.

When you accelerate water under pressure, Bernoulli effect says the pressure drops as the speed of flow increases. This would increase the effective pressure differential between Earth and Narnia, thereby increasing the flow rate through the wardrobe.

I can't believe I just did that.
