A multi-lane highway is operating in a high mountain valley on a typical grade of about 1%, or grades representing level terrain conditions. It is carrying 10% trucks. The passenger car equivalent is 1.5 for level terrain, and 2.5 for rolling terrain and 4.0 for mountainous terrain. What is the heavy vehicle factor, f.

How does this peak flow calculator work?
This is a quick health tool that determines the estimated or predicted peak flow based on your data.
You need to select your gender and input your age and height. The former can be put in either metric (cm) or English (inches) measurement.
If you already have a peak flow determination you can input that as well to get an extra info in the result.
Peak Hour 4
Based on peak flow formulas, the calculator computes the predicted value in your case and extracts the percentage the measured figure is out of the prediction. You can use the form as many times as you like varying the information or personal data. Hydra 4 0 download free.
Example calculation:
■ Let’s take for instance the case of a female aged 32 with a height of 175cm. Her estimated peak flow value would be 467.4 L/min.
■ Or in the case of a male aged 27 with a height of 186 cm. His predicted peak flow value would be 639.948 L/min. But if he already has a measured peak flow of 568 L/min, the percentage is 88.76.
