Total Critical Energy Solution

STEP 0: Pre-Calculation Summary

Formula Used

Energy at critical point = (Critical Depth+(((Critical Velocity)^2)/(2*Acceleration due to Gravity))+(0.1*((Critical Velocity)^2/(2*Acceleration due to Gravity))))
E_c = (CD+(((V_c)^2)/(2*g))+(0.1*((V_c)^2/(2*g))))
This formula uses 4 Variables

Variables Used

Energy at critical point - (Measured in Meter) - Energy at critical point is the total energy (both potential and kinetic energy) at the point of jump formation.
Critical Depth - (Measured in Meter) - Critical depth occurs when the flow in a channel has a minimum specific energy. Specific energy refers to the sum of the depth of flow and the velocity head.
Critical Velocity - (Measured in Meter per Second) - The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.
Acceleration due to Gravity - (Measured in Meter per Square Second) - Acceleration due to Gravity is acceleration gained by an object because of gravitational force.

STEP 1: Convert Input(s) to Base Unit

Critical Depth: 4 Meter --> 4 Meter No Conversion Required
Critical Velocity: 15 Meter per Second --> 15 Meter per Second No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E_c = (CD+(((V_c)^2)/(2*g))+(0.1*((V_c)^2/(2*g)))) --> (4+(((15)^2)/(2*9.8))+(0.1*((15)^2/(2*9.8))))

Evaluating ... ...

E_c = 16.6275510204082

STEP 3: Convert Result to Output's Unit

16.6275510204082 Meter --> No Conversion Required

FINAL ANSWER

16.6275510204082 ≈ 16.62755 Meter <-- Energy at critical point

Total Critical Energy Formula

What is critical energy ?

The excitation energy must be above a particular value for certain nuclide. The minimum excitation energy required for fission to occur is known as the critical energy (Ecrit) or threshold energy.

How to Calculate Total Critical Energy?

Total Critical Energy calculator uses Energy at critical point = (Critical Depth+(((Critical Velocity)^2)/(2*Acceleration due to Gravity))+(0.1*((Critical Velocity)^2/(2*Acceleration due to Gravity)))) to calculate the Energy at critical point, The Total Critical Energy is defined as the minimum excitation energy required for fission to occur. Energy at critical point is denoted by E_c symbol.

How to calculate Total Critical Energy using this online calculator? To use this online calculator for Total Critical Energy, enter Critical Depth (CD), Critical Velocity (V_c) & Acceleration due to Gravity (g) and hit the calculate button. Here is how the Total Critical Energy calculation can be explained with given input values -> 16.62755 = (4+(((15)^2)/(2*9.8))+(0.1*((15)^2/(2*9.8)))).

FAQ

What is Total Critical Energy?

The Total Critical Energy is defined as the minimum excitation energy required for fission to occur and is represented as E_c = (CD+(((V_c)^2)/(2*g))+(0.1*((V_c)^2/(2*g)))) or Energy at critical point = (Critical Depth+(((Critical Velocity)^2)/(2*Acceleration due to Gravity))+(0.1*((Critical Velocity)^2/(2*Acceleration due to Gravity)))). Critical depth occurs when the flow in a channel has a minimum specific energy. Specific energy refers to the sum of the depth of flow and the velocity head, The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent & Acceleration due to Gravity is acceleration gained by an object because of gravitational force.
