# Calculating gauge pressure in lungs to produce certain speeds

#### tooperoo

1. Homework Statement
The human sneeze can reach speeds of 150km/hr. Calculate the gauge pressure in the lungs required to generate a flow with this speed at atmospheric pressure. Assume the density of the air is constant at 1.3 kg/m^3.

2. Homework Equations

3. The Attempt at a Solution

I tried solving to get the gauge pressure but i need the height to do this. Also, i tried working with fluid formulas that have velocity in them but i keep getting stuck due to not having all the variables.

I would think you could use the Bernoulli equation with the speed in the lungs set to zero. After all it starts out stationary.

I might give that a go bud. Thanks!
