SUMMARY

This discussion focuses on calculating the inlet pressure required to achieve a desired outlet pressure of 4 bars using a Diesel Water Pump with a flow rate of 1000 GPM. The calculations consider a standard hose length of 30 meters and a diameter of 2.5 inches. Users are directed to reference the "Determination of Fire Hose Friction Loss Characteristics - NFPA" for friction loss data relevant to rubber hoses. Accurate calculations are essential for ensuring optimal pump performance and achieving the target pressure.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with pressure measurement units (bars, GPM)
  • Knowledge of hose specifications and friction loss calculations
  • Experience with Diesel Water Pumps and their operational parameters
NEXT STEPS
  • Research "friction loss calculations for hoses" to understand pressure drop over distance
  • Study "pump performance curves" to correlate flow rate and pressure
  • Explore "hydraulic calculations for water systems" for comprehensive analysis
  • Investigate "NFPA guidelines on fire hose specifications" for industry standards
USEFUL FOR

This discussion is beneficial for engineers, technicians, and anyone involved in fluid mechanics, particularly those working with water pumps and hose systems in industrial or firefighting applications.

So i have this Diesel Water pump, i need to achive a pressure of 4 bars at the end of the hose, How to calculate the pressure in inlet to achieve the desired result of 4 bars at outlet.
(Assuming that I'm using a standard hose of length 30metres, with a diameter of 2.5 inches)
Pump FLOW RATE IS Q=1000GPM
