Area, volume and depth relation?

Click For Summary
SUMMARY

The discussion centers on calculating the depth of water collected in a raingauge orifice based on its area and the volume of water it collects. The formula V = A*h is established, where V represents volume, A is the area of the orifice, and h is the height (or depth) of the water. Participants emphasize the need for additional dimensions, specifically the diameter of the orifice and the cylinder, to accurately determine the depth. The conversation highlights the relationship between area, volume, and depth in fluid measurement systems.

PREREQUISITES
  • Understanding of basic geometric formulas, specifically volume calculations.
  • Familiarity with the concept of cross-sectional area in fluid dynamics.
  • Knowledge of raingauge design and functionality.
  • Ability to manipulate algebraic equations for problem-solving.
NEXT STEPS
  • Research the design and operation of various types of raingauges.
  • Learn about fluid dynamics principles, particularly related to volume and area calculations.
  • Explore advanced geometric formulas for irregular shapes in fluid measurement.
  • Investigate the impact of orifice shape on water collection efficiency.
USEFUL FOR

This discussion is beneficial for engineers, hydrologists, and anyone involved in designing or analyzing raingauge systems and fluid measurement devices.

Area, volume and depth relation?
Im given a object, which is a raingauge orifice. it has an area of a certain value. This object collects x amount of water. How do i find a depth from these given values?

Is there a formula for calculating depth?

I think we need more information. Most raingauges I have seen look like a funnel that feeds rainwater into a glass or plastic cylinder with graduated markings. The idea is that the funnel collects rain water over a relatively large cross-sectional area, and feeds into a cylinder with a smaller cross section. This makes it easier to measure a rainfall of, say .01 inch.

If the raingauge you're talking about is something like what I've described, we need to know the diameter of the top at its widest part and the diameter of the cylinder.
 
im not given any dimensions. All i get in the question is the orifice area and that it collects certain volume of rain water over a period of time.
 
OK, assuming the gauge is a cylinder (not necessarily round), volume is related to the orifice area and height of the gauge by this formula: V = A*h.
