SUMMARY

The discussion focuses on calculating the pressure required to release 400ml of hydraulic oil from a cylinder in 10 seconds. The setup involves a cylinder with a height of 300mm and a diameter of 80mm, connected to a 2m length pipe with a 12mm diameter exit. The density of the hydraulic oil is specified as 900kg/m³. Participants recommend using Bernoulli's Principle to determine the necessary head for achieving the desired flow rate while considering head losses due to pipe friction and minor losses.

PREREQUISITES
  • Understanding of Bernoulli's Principle
  • Knowledge of fluid dynamics and flow rates
  • Familiarity with hydraulic systems and components
  • Ability to calculate head losses in pipes
NEXT STEPS
  • Research how to apply Bernoulli's Principle in practical scenarios
  • Learn about calculating head losses due to pipe friction
  • Explore flow rate calculations for hydraulic systems
  • Investigate the impact of pipe diameter on flow rates
USEFUL FOR

Engineers, fluid dynamics specialists, and anyone involved in hydraulic system design and optimization will benefit from this discussion.

hi good day everyone,

Typically i have a 300mm height, 80mm diameter cylinder filled with 400ml hydraulic oil. It connected to 2m length pipe via 12mm diameter exit. Density of hydraulic oil is assumed to be 900kg/m^3. My task is to release the 400ml hydraulic oil in 10seconds. So in this case how could i figure out and measure the desired vertically pressure pls?! thanks in advanced :confused:kinki_ania@hotmail.com

Use Bernoulli's Principle and account for the head losses (pipe friction and minor losses) and determine the required head needed for the desired flow rate. It may take some iteration.
