Specific weight and volume question

Click For Summary
SUMMARY

The discussion centers on calculating the added weight of water in tanks with a specific weight of 9.45 kN/m³. The user seeks clarification on how to compute the added weight based on varying tank volumes. The correct approach involves multiplying the specific weight by the volume of water in each tank to determine the total weight in kilonewtons (kN). This method ensures accurate unit consistency and provides the necessary data for plotting the added weight against tank sizes.

PREREQUISITES
  • Understanding of specific weight and its units (kN/m³)
  • Basic knowledge of volume calculations for cylindrical tanks
  • Familiarity with plotting data on graphs
  • Ability to perform unit conversions and dimensional analysis
NEXT STEPS
  • Learn how to calculate the weight of liquids using specific weight and volume
  • Explore the principles of fluid mechanics related to buoyancy and weight
  • Study how to create graphs and plots using software like Excel or MATLAB
  • Investigate dimensional analysis to ensure unit consistency in calculations
USEFUL FOR

Students in engineering or physics, educators teaching fluid mechanics, and anyone involved in designing or analyzing tank systems for liquids.

Homework Statement


So I have a problem/question were tanks are filled with water and its specific weight is 9.45 kN/m^3. They also give you a range of volumes of different tanks. The problem then asks for the plot of added weight (kN) due to the liquid for the given range of the different tank sizes (diameter). My question is how do you get the added weight; do I just add the different volumes to the specific weight. Thanks for the help.

Homework Equations


no equations given

The Attempt at a Solution


Adding the different volumes to the specific weight

This question as paraphrased doesn't make a lot of sense.

Can you post the exact wording of the question, including any data or figures included in the problem statement?
