Enter the surface area (ft^2) and the effective production rate (ft^2/min) into the Sandblasting Time Calculator. The calculator will evaluate the Sandblasting Time.

## Sandblasting Time Formula

The following two example problems outline the steps and information needed to calculate the Sandblasting Time.

SNDT = SA / EPR

Variables:

• SNDT is the Sandblasting Time (minutes)
• SA is the surface area (ft^2)
• EPR is the effective production rate (ft^2/min)

To calculate the sandblasting time, divide the surface area by the effective production rate.

## How to Calculate Sandblasting Time?

The following steps outline how to calculate the Sandblasting Time.

1. First, determine the surface area (ft^2).
2. Next, determine the effective production rate (ft^2/min).
3. Next, gather the formula from above = SNDT = SA / EPR.
4. Finally, calculate the Sandblasting Time.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

surface area (ft^2) = 40

effective production rate (ft^2/min) = 3

SNDT = SA / EPR = ?
