The weight of the water must equal the difference in pressure.
atmospheric pressure-his pressure=weight 2M water.
101.3kPa*area-hispressure*area=area*2m*densitywater*g
101.3kpa-hispressure=
2m*10^3kg/m^3*9.8N/kg
his pressure=101.3kpa-18.6kPa
check my figuring.
The highest that George can suck water up a very long straw is 2.0 m. (This is a typical value.)
What is the lowest pressure that he can maintain in his mouth?

you's the best
Sorry, I meant you are the BEST
There is an error. 2*9.8=19.6, not 18.6
change that.
