## Packer Testing: Is the flow laminar in my test?

This article is about a small but critical check that we should do when conducting packer testing. That is, whether the flow is laminar during the test. The ground water manual talk about how to check for the laminar nature…

## Python GUI for Molarity, Meq and Equivalent Weight: Calculator

I am going to talk about molarity (moles/L) , mili-equivalent/L and equivalent weight today. My approach is to get you what you need from common geochemical analysis report from various labs in the US. In general, when you analyze for…

## Python GUI: Darcy’s Law – calculate Flow, Specific Discharge and Average Linear Velocity

Hi all. Today I will demonstrate how to develop a simple GUI tool for calculating discharge, specific discharge and average linear velocity using Python. I will be using codeskulptor as my online tool. Make sure that you are NOT using…

## Python GUI for surface hydrology: Calculate Recession Constant online [Example solution to Fetter Hydrogeology]

Today I am going to show you another computer application in hydrogeology, more specifically – in surface hydrogeology. In many projects, it is crucial to monitor flow. Flow generally varies over time and respond to rainfall events. It also varies…

## GUI: Function for the discharge equation by Addition in 1949

I have upgraded my Python code to include a graphical user interface. Here is the code:   Run the program online here: http://www.codeskulptor.org/#user21_ikyPgf2883_1.py import simplegui C,L,H,n=0,0,0,0 C_str, L_str,H_str,n_str=”,”,”,” result=0 result_str=” # Handler for mouse click # Handler to draw on canvas…

## Python Function to calculate Weir Discharge

Weirs are commonly used to measure flow at small creeks and other flow systems. We have developed a simple Python function to calculate the discharge from a weir “discharge_weir(C,L,H,n)”. We will check our results using two formulas -Addition formula and…
