This tool was developed for the APRCO engineers to evaluate the performance of their centrifugal pumps in their respective units.
You need 3 files/entries to use this tool:
- FAT (factory acceptance test) results of you pump (Q, H, Power, Efficiency%)
- your pump motor datasheet data (Load%, Current, motor efficiency and power factors)
- performance test data (Q, Psuc.,Pdisch., Current, Voltage and Specific gravity)[1]
The App will fit your FAT Q-H and Q-Efficiency data into two curves using the Equation described as follows [2]: H = aQ + bQ^2 + C E = aQ + bQ^2 + C
Then performs your performance test calculations and calculate %Error in your readings (Compare it with API 610 tolerance table) Additionally, the app will display your test results in graphs and you can also download your calculations table!
[1] P.S: you can make an estimate of your fluid Specific gravity using the shut-off head in your characteristic curve where dP (Pa) = rho9.81H (m) usually makes +-8% Error in S.G. [2] Working Guide to Pump and Pumping Stations: Calculations and Simulations, E. Shashi Menon - Pages (25-27)
Note 1: These calculations neglects the effects of elevations differences between your to pressure gauges. Note 2: add form code credits: Mr. Shawn_Pereira reply in discuss.streamlit.io link: https://discuss.streamlit.io/t/how-to-add-records-to-a-dataframe-using-python-and-streamlit/19164/5
