Homework Statement



Cylindrical tank of water is 20m tall, and full. atmospheric pressure is 1.01x10^5 Pa and the density of water is 1000Kg/m^3. Find absolute pressure 6m above the bottom.

Homework Equations



P=P*sub*a + pgh

The Attempt at a Solution



I got so far... P=(1.01 x 10^5) + (1000)g(6)
How do i find g?????what is g????????????

Isn't g gravity? Which is a given constant most of the time.

Good point. The water tank is 20 m high and the gauge is 6 m above the base so how many meters below the water line is it?
