Energy Recovery Effectiveness Calculator

Calculate Energy Recovery Effectiveness



Formula

The formula to calculate the energy recovery effectiveness (E) is:

\[ E = \left( \frac{ER}{M} \right) \times 100 \]

Where:

Definitions

Example

Let's say the energy recovered (ER) is 500 units and the maximum possible energy recovery (M) is 1000 units. Using the formula:

\[ E = \left( \frac{500}{1000} \right) \times 100 \]

We get:

\[ E = 50\% \]

So, the energy recovery effectiveness is 50%.

Energy Efficiency Cost Recovery Factor

Definition: The cost recovery factor measures the payback period for energy efficiency investments.

Formula: \( \text{CRF} = \frac{r(1+r)^n}{(1+r)^n - 1} \)

Example: \( \text{CRF} = \frac{0.05(1+0.05)^{10}}{(1+0.05)^{10} - 1} \)

Equation for Percent Recovery

Definition: Percent recovery is the percentage of the initial amount of a substance that is recovered after a process.

Formula: \( \text{Percent Recovery} = \frac{\text{Recovered Amount}}{\text{Initial Amount}} \times 100 \)

Example: \( \text{Percent Recovery} = \frac{80}{100} \times 100 \)

Energy Efficiency Rating Calculator

Definition: This calculator determines the energy efficiency rating of a system based on its energy input and output.

Formula: \( \text{Efficiency} = \frac{\text{Energy Output}}{\text{Energy Input}} \times 100 \)

Example: \( \text{Efficiency} = \frac{900}{1000} \times 100 \)

Estimated Ultimate Recovery Formula

Definition: Estimated ultimate recovery (EUR) is the total amount of resource expected to be recovered from a reservoir.

Formula: \( \text{EUR} = \text{Initial Production} \times \text{Decline Rate} \)

Example: \( \text{EUR} = 1000 \times 0.85 \)

Heat Recovery Calculation Formula

Definition: This formula calculates the amount of heat recovered in a heat recovery system.

Formula: \( Q = \dot{m} c_p \Delta T \)

Example: \( Q = 2 \times 4.18 \times 50 \)

Calculation of Energy Efficiency

Definition: Energy efficiency is the ratio of useful energy output to the total energy input.

Formula: \( \eta = \frac{\text{Useful Energy Output}}{\text{Total Energy Input}} \)

Example: \( \eta = \frac{800}{1000} \)
