Calculating Water Volume in a Tank Using Pressure Measurements

Click For Summary

Homework Help Overview

The problem involves calculating the volume of water in a cubic aquarium based on pressure measurements. The aquarium has a total volume of 640 cm³, and the pressure at the bottom is stated to be three times greater than the pressure on one side. Participants are exploring how to relate these pressures to the depth of water in the tank.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the interpretation of the pressure measurements and question the clarity of the problem statement. There is exploration of how pressure varies with depth and how to express the forces acting on the sides and bottom of the tank. Some participants suggest using integration to find the total force on a strip at varying depths.

Discussion Status

There is an ongoing exploration of the relationships between pressure, force, and depth. Participants are attempting to derive expressions for the forces acting on the tank and are questioning how to find the depth of water based on the given information. Some guidance has been offered regarding the integration of forces, but no consensus has been reached on the final approach.

Contextual Notes

Participants note that the problem's wording may lead to different interpretations, particularly regarding the uniformity of pressure on the sides of the tank. There is also mention of constraints related to the dimensions of the tank and the relationship between the forces acting on the bottom and sides.

I made a mistake, L is 40cm, 64dm3 is not 640cm3 it's 64000cm3. It's because we're dealing with volume not length.

Don't worry . Just be more rigorous with you methods when doing future problems .

All done .
