Help Needed: Calculating Air Pressure with Roe and K

Click For Summary
SUMMARY

This discussion centers on calculating air pressure using the parameters provided by a student, Benjamin, who is struggling with his physics homework. The relevant values given are ρ (rho) = 1.29 kg/m³ and k = 1.4. The forum emphasizes the importance of understanding the relevant equations and encourages students to attempt solutions independently rather than seeking direct answers. The discussion highlights the educational approach of promoting self-learning and problem-solving skills in physics.

PREREQUISITES
  • Understanding of basic physics concepts, particularly fluid dynamics.
  • Familiarity with the ideal gas law and related equations.
  • Knowledge of the Greek letter ρ (rho) and its significance in fluid density.
  • Ability to perform calculations involving air pressure and temperature conditions.
NEXT STEPS
  • Research the ideal gas law and its application in calculating air pressure.
  • Learn about the relationship between density (ρ), temperature, and pressure in gases.
  • Study the concept of specific heat ratios, particularly the significance of k = 1.4.
  • Practice solving problems related to air pressure using provided formulas and examples.
USEFUL FOR

This discussion is beneficial for high school physics students, educators teaching fluid dynamics, and anyone looking to enhance their understanding of air pressure calculations.

Hello everybody... My name is Benjamin and I'm new on this forum... I come from Bosnia & Herzegovina...


Our new school year just started... and first day we get some homework in psyhics to do... its all from 1 grade (1st year of school) and its about air preassure... I would like your help just with this task because I just can't remember formulas just can't...


it says: Calculate air preassure at normal conditions where roe(greece letter known as ro ggl it) so. roe= 1.29(kg/m^3)... and k=1.4 that's all that our professor gave to us please help me I need help just this one

Welcome to the PF.

We do not do your schoolwork for you here. What are the relevant equations involved (you can find them in your textbook), and what is your attempt at a solution?
