This script is designed to calculate the parameters of a pump system for a single section with the following initial conditions:
- Temperature: 29°C
- Level of the charging point with respect to the pump: -19 m
- Level of the discharge point above the pump: 38 m
- System inlet pressure: 12 psig
- System discharge pressure: 20 psig
- System pipe: 6 in DN SCH 40
- Total pipe length: 340 m
- Working flow: 410 GPM
- The working fluid is WATER, in a COMMERCIAL STEEL pipe
The script will prompt you to enter the data with the specified units. Please note that if you enter a value that is not within the requested parameters, the algorithm will not give a valid response or will stop.
The script starts with the following initial conditions:
- Temperature: 302 K
- Level at the beginning (yi): -19 m
- Level at the end (yf): 38 m
- Initial pressure: 82714.2857 Pa
- Final pressure (pf): 137857.1429 Pa
- Initial velocity (vi): 0 m/s
The properties of the pipe and the fluid are as follows:
- Viscosity: 0.00084225 Pa s
- Density: 995.5 kg/m3
- Roughness: 0.00000381 m
- Diameter: 0.154051 m (This is from 6 in DN SCH 40)
- Volumetric flow: 0.02586698565 m3/s
- Length of the section: 340 m
The script calculates the work and power required for the pump system. It also calculates the saturation pressure in the pump using Antoine's constants for Temperature in °C and Pressure in kPa.
Based on the calculated parameters, the script will suggest a suitable pump and provide an option to view the design and more information about the pump.
Please note that this script is designed for a specific set of initial conditions and may not give accurate results for different conditions. Always verify the results with a qualified engineer or consultant.
