Calculating Oil Flow Speed: Density 850 kgm^3, Pipe Diameter 8 cm

Click For Summary
SUMMARY

The discussion focuses on calculating the speed of oil flowing through a pipe with a diameter of 8 cm and a density of 850 kg/m³ at a rate of 9.5 liters per second. The speed is determined using the formula v_1 = (dv/dt)/a_1, resulting in a flow speed of 1.9 m/s. The conversion factor of 10^-3 is essential for changing liters to cubic meters, as 1 liter equals 0.001 cubic meters. This conversion is crucial for accurate calculations in fluid dynamics.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of unit conversions, specifically liters to cubic meters
  • Familiarity with the formula for flow speed in a pipe
  • Basic calculus for interpreting rates of change
NEXT STEPS
  • Study fluid dynamics equations, particularly the continuity equation
  • Learn about unit conversion techniques in physics
  • Explore applications of the Bernoulli equation in fluid flow
  • Investigate the impact of pipe diameter on flow speed and pressure
USEFUL FOR

Students in physics or engineering courses, professionals in fluid mechanics, and anyone involved in calculating flow rates in piping systems will benefit from this discussion.

Homework Statement


oil w/ density of 850 kgm^3 goes through a pipe diameter 8 cm at a rate of 9.5 liters / s.
what is the speed of the oil?


Homework Equations



v_1 = (dv/dt)/a_1 = (9.5*10^-3)/(pi(.04)^2) = 1.9 m/s

The Attempt at a Solution



i have the solution because this problem was given to me. I just don't understand where the 10^-3 came from and how it was derived.

It comes from converting the volume from litres into m^3.
