🔍 Key Concepts

• Hydrostatic pressure in a liquid column (pressure increases with depth: deeper = more pressure) • How a bubbler / air bell level indicator works (air pressure balances liquid head H) • Relationship between pressure and height of a liquid: $P = \rho g H$

💭 Think About

• When you squeeze bulb B and send air down to point E, what must the air pressure in line D become before bubbles can escape from under the bell? • Once that pressure is reached and held, what does gage C actually measure: the tank’s depth directly, the pressure at D, or something related? • If you doubled the liquid height H in the tank, what would happen to the pressure at D, and therefore to the reading in gage C?

✅ Before You Answer

• Verify that the pressure at D depends only on the vertical height H of liquid above point E, not on the tank’s shape or volume. • Check whether the gage C is responding to pressure or directly to liquid height in the tank. • Confirm that for a given liquid of constant density, pressure and height are linearly related (proportional), using $P = \rho g H$ .

The illustrated device operates on the principle that the height of the liquid in gage "C" is __________. See illustration GS-0066.

directly equal to the height of the liquid in the tank

proportional to the height of the liquid, H

equal to the fluid pressure supplied at D after a small portion of the fluid from the tank forced into column C

proportional to the pressure of the cube root of the height of liquid H, times .491
