Enter the total number of horizontal lines displayed and the time (sec) into the Calculator. The calculator will evaluate the Horizontal Scan Rate. 

Horizontal Scan Rate Formula

HSR = HL / T


  • HSR is the Horizontal Scan Rate (lines/sec)
  • HL is the total number of horizontal lines displayed
  • T is the time (sec)

To calculate the Horizontal Scan Rate, divide the total number of lines by the time.

How to Calculate Horizontal Scan Rate?

The following steps outline how to calculate the Horizontal Scan Rate.

  1. First, determine the total number of horizontal lines displayed. 
  2. Next, determine the time (sec). 
  3. Next, gather the formula from above = HSR = HL / T.
  4. Finally, calculate the Horizontal Scan Rate.
  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.

total number of horizontal lines displayed = 800

time (sec) = 5


What is the significance of the hydration rate in baking?

The hydration rate is crucial in baking as it determines the dough’s consistency, affecting the texture and quality of the baked goods. A higher hydration rate typically leads to a looser dough and a more open crumb structure in the final product.

Can the hydration rate affect the flavor of baked goods?

Yes, the hydration rate can influence the flavor of baked goods. Higher hydration levels can enhance enzyme activity, which can lead to a more complex flavor development during fermentation and baking.

Is it possible to adjust the hydration rate for different types of flour?

Yes, different types of flour absorb water differently, so adjustments to the hydration rate may be necessary. Whole grain flours, for example, tend to absorb more water than white flours, requiring a higher hydration rate for comparable dough consistency.

How does the hydration rate impact the baking time and temperature?

Doughs with a higher hydration rate may require a longer baking time at a potentially lower temperature to ensure thorough baking and desirable crust development. It’s important to adjust baking parameters based on the dough’s hydration level.
