A4_7 Who's up for a Ride on the Volcano?

Abstract

Using Bernoulli's theorem for incompressible fluids we calculate the required pressure and velocity of gas and ash in a volcanic eruption chamber needed to propel Manny the mammoth skywards out of a lava-filled crater. We calculate that a pressure of 14.7 MPa, and an outflow velocity of 112.6$ ms^-1 are required.
