The discussion revolves around calculating the pressure at the bottom of a tank filled with water, given the volume of ethyl alcohol that has the same mass. Participants are exploring the relationships between density, volume, and pressure in the context of fluid mechanics.
Several participants have provided insights into the calculations, with some suggesting the need to consider atmospheric pressure in their equations. There is an ongoing exploration of how to correctly apply the formulas for pressure and density, with no clear consensus yet on the correct approach.
Participants are working under the constraints of a homework assignment, which may impose specific requirements for the calculations, such as the need to express pressure in different units. There is also confusion regarding the dimensions of the tank and the appropriate density to use for the calculations.
Calculate what? You are given Pb and you know Pa.talaroue said:
See post #27. That's what we've been talking about.talaroue said:
Hint: What's atmospheric pressure in units of atm?talaroue said:
Sure. Note that the pressure at the bottom is given in units of atm.talaroue said:
