• Angle of Repose Calculation - The angle of repose calculation determines the steepest angle at which a pile of granular material remains stable based on its friction properties.
• Foliation Angle in Metamorphic Rocks - This formula calculates the foliation angle in metamorphic rocks based on the angle of intersection and the slope of the rock.
• Groundwater Table Gradient Calculation - The groundwater table gradient measures the change in groundwater level over a certain distance. This calculator helps in understanding the flow and movement of groundwater.
• Plate Tectonic Velocity Equations - The plate tectonic velocity equation calculates the velocity of tectonic plate movement based on the distance and time taken.
• Porosity Formula - The porosity of a material is a measure of the void spaces in the material, expressed as a percentage. This calculator helps determine porosity.
• Schmid Factor (for crystallographic planes) - The Schmid factor is a dimensionless quantity that describes the favorability of slip on a specific crystallographic plane in a particular crystal structure.
• Shear Stress in Rocks - Calculate the shear stress in rocks using the applied force and area with this calculator.
• Strain Tensor Equations - The strain tensor is a mathematical representation of the deformation of a material and is used in continuum mechanics to describe the displacement and distortion of material particles.
• Stream Discharge - The stream discharge is calculated by multiplying the cross-sectional area of the stream by the velocity of the water flow. This calculator helps find the discharge of a stream.
• Thermal Conductivity in Geological Materials - The thermal conductivity in geological materials is calculated using a specific formula. This calculator helps understand heat flow through geological materials.
