Groundwater gradient is calculated by the equation: i=dh/dl Where: i= groundwater gradient d= the change in, or Delta h= groundwater head l= length of casing in the well Using this you would take two wells, use the well log to determine the length (ie. depth) of each well, and subtract the first from the second. That's dl. On a particular date or time (must be the same time/date for both wells), you determine the groundwater elevations in the two wells and subtract the first from the second. That's dh. Divide dh by dl, the answer is your gradient. The gradient is dimensionless, if it's positive groundwater is flowing upward (vertically) in the direction of the first well to the second well, if it's negative, groundwater is flowing downward (vertically) in the direction of the first well to the second well.

How to calculate the gradient from the non linear graph?
Draw a tangent to the curve at the point where you need the gradient and find the gradient of the line by using gradient = up divided by across
How do you calculate the ratio of force to extension from the gradient of a graph?
The answer will depend on what variables are graphed!
How do you calculate transversal lines?
Transversal lines are not parallel and so have a gradient that is different to that of the given lines.
How do you read and calculate speed from a motion graph?
You can calculate speed by taking the gradient (dy/dx) from a Distance-time graph since s=d/t
How does groundwater depth and hydrostatic pressure gradient affect bacteria?
i have pressure right now
How do you calculate gradient?
Gradient= Vertical gain / Horizontal distance Hope this helps ;P

What force pushes groundwater from pore to pore below the water table?
Pressure gradient or hydraulic gradient is the force that pushes groundwater from pore to pore below the water table. A boundary between saturated rock below and unsaturated rock above is the water table.

How do you calculate gradient for drainage if floor levels are given?
suppose you have a gradient of (1:40) divide 1000mm by 40mm = 25mm so for every meter run gradient fall by 25mm till you get to the invert level. That's it.
How do you calculate the slope of a graph?
Using limits and the basic gradient formula: rise/run.
How do you calculate transpulmonary gradient?
Mean PA pressure divided by Fick cardiac output
How do you calculate transversal lines?
Transversal lines are not parallel and so have a gradient that is different to that of the given lines.
