Enter the shaft speed (m/s) and the temperature (K) into the Calculator. The calculator will evaluate the Corrected Speed. 

Corrected Speed Formula

CS = SF / SQRT(T/288.15)

Variables:

  • CS is the Corrected Speed (m/s)
  • SF is the shaft speed (m/s)
  • T is the temperature (K)

To calculate the Corrected Speed, divide the shaft speed by the square root of the temperature over 288.15.

How to Calculate Corrected Speed?

The following steps outline how to calculate the Corrected Speed.


  1. First, determine the shaft speed (m/s). 
  2. Next, determine the temperature (K). 
  3. Next, gather the formula from above = CS = SF / SQRT(T/288.15).
  4. Finally, calculate the Corrected Speed.
  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.

shaft speed (m/s) = 89

temperature (K) = 200

FAQs about Corrected Speed Calculation

What is the significance of using the Corrected Speed formula in engineering?
The Corrected Speed formula is crucial in engineering because it accounts for temperature variations that affect the physical properties of materials and the efficiency of machines. By using this formula, engineers can ensure that their calculations and designs are more accurate and reliable under different operating temperatures.

How does temperature affect shaft speed in machinery?
Temperature can significantly impact shaft speed in machinery. As temperature increases, materials may expand, and the efficiency of mechanical components can decrease, leading to changes in shaft speed. Correcting for temperature allows for more consistent and predictable machinery performance.

Can the Corrected Speed formula be applied to any type of machinery?
While the Corrected Speed formula is broadly applicable, its relevance and accuracy may vary depending on the type of machinery and its operating conditions. It is most useful for machinery where temperature fluctuations can significantly impact performance, such as in turbines, compressors, and engines.

Why is 288.15 used in the Corrected Speed formula?
The value 288.15 K is used in the Corrected Speed formula as it represents the standard temperature in Kelvin at sea level according to the International Standard Atmosphere (ISA). This standard reference point allows for consistent calculations and comparisons across different scenarios and environments.
