Re: [Phys-l] Entrainment of oil in Hurricane?



Ah yes, I thought this might be the unspoken concern. It's a physics thing - that water cannot be pumped up more than 33 feet in a suction pump. The engineer's way of suction-pumping water up more than twice that Torricellian limit, is by adjusting the water-density that the pump has to deal with.

obviously Bob L. is correct. [I also found such in googling.] A perfect tornado (note: true water spouts are nothing compared to tornados over water) would support only about 34 feet of water as Torricelli found. (earlier others more properly:
