Khosla Derived Expression for Exit Gradient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Exit Gradient = (Total Seepage Head/Depth of Floor)*(1/(3.14*sqrt(Constant Value for Exit Gradient)))
G_E = (H/d)*(1/(3.14*sqrt(λ)))
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Exit Gradient - Exit gradient of the pressure of water at the exit end.
Total Seepage Head - (Measured in Meter) - Total seepage head movement of water through the soil.
Depth of Floor - (Measured in Meter) - Depth of floor is of one level of a home shares framing with the ceiling of the level below it.
Constant Value for Exit Gradient - Constant value for exit gradient.

STEP 1: Convert Input(s) to Base Unit

Total Seepage Head: 2.4 Meter --> 2.4 Meter No Conversion Required
Depth of Floor: 4.277 Meter --> 4.277 Meter No Conversion Required
Constant Value for Exit Gradient: 5.203 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

G_E = (H/d)*(1/(3.14*sqrt(λ))) --> (2.4/4.277)*(1/(3.14*sqrt(5.203)))

Evaluating ... ...

G_E = 0.0783457478426837

STEP 3: Convert Result to Output's Unit

0.0783457478426837 --> No Conversion Required

FINAL ANSWER

0.0783457478426837 ≈ 0.078346 <-- Exit Gradient

Correction for Mutual Interference of Pile

Go Correction to be Applied as Percentage of Head = 19*sqrt(Depth of Pile Effect is Required on Neighbor Pile/Distance Between the Piles)*((Depth of Pile on Which Effect on Neighbor Pile+Depth of Pile Effect is Required on Neighbor Pile)/Total Length of Floor)

Khosla Derived Expression for Exit Gradient

Go Exit Gradient = (Total Seepage Head/Depth of Floor)*(1/(3.14*sqrt(Constant Value for Exit Gradient)))

Khosla Derived Expression for Exit Gradient Formula

Exit Gradient = (Total Seepage Head/Depth of Floor)*(1/(3.14*sqrt(Constant Value for Exit Gradient)))
G_E = (H/d)*(1/(3.14*sqrt(λ)))

What is Exit Gradient and Critical Exit Gradient?

Critical exit gradient is the ratio of seepage head loss to the length of seepage it means it is not related to specific gravity or voids ratio. It is directly proportional to head loss and inverse to the length of seepage.

What is the importance of Exit Gradient?

Increasing the seepage velocity at the downstream end of hydraulic structures may cause the movement of soil particles and accordingly accelerates piping and soil erosion. The exit gradient is the main design criterion in determining the safety of hydraulic structures against the piping phenomenon.

How to Calculate Khosla Derived Expression for Exit Gradient?

Khosla Derived Expression for Exit Gradient calculator uses Exit Gradient = (Total Seepage Head/Depth of Floor)*(1/(3.14*sqrt(Constant Value for Exit Gradient))) to calculate the Exit Gradient, The Khosla Derived Expression for Exit Gradient formula is defined as the soil grain remaining stable; the submerged weight of the soil grain should be more than this upward force. This force at any point is proportional to the gradient of the pressure of water at that point. Exit Gradient is denoted by G_E symbol.

How to calculate Khosla Derived Expression for Exit Gradient using this online calculator? To use this online calculator for Khosla Derived Expression for Exit Gradient, enter Total Seepage Head (H), Depth of Floor (d) & Constant Value for Exit Gradient (λ) and hit the calculate button. Here is how the Khosla Derived Expression for Exit Gradient calculation can be explained with given input values -> 0.078346 = (2.4/4.277)*(1/(3.14*sqrt(5.203))).
