About
Calculate air velocities in fabric ducting and diffusers based on airflow and size. Visual color cues indicate velocity suitability, with red for unacceptable and green for suitable. Adjust dimensions and units easily for precise calculations.
What's New in Prihoda
1.2
September 30, 2017
This app has been updated by Apple to display the Apple Watch app icon. In order to correctly design the air distribution, it is necessary to know the reach of flows from perforation. These values are determined by entering the static pressure in the duct along with its length and selecting the cross section angle that will be filled by the perforation. The axial flowing speed in the selected distance from the duct is shown on the scale. Alternatively, you can find the distance at which the speed has a certain value. The next screen will show you an illustration of the distribution of speed zones of the whole air flow.

What is Prihoda used for?
Prihoda is used for calculating air velocities in fabric ducting and diffusers. It helps determine the suitability of calculated velocities based on airflow and duct size.
How does Prihoda indicate velocity suitability?
Prihoda uses a color scale: red for unacceptable, orange for risky, green for suitable, and blue for excessively dimensioned velocities. This provides an immediate visual cue for performance.
Can I adjust the duct size and airflow in Prihoda?
Yes, you can enter values by moving a ruler or typing specific numbers for both airflow and duct size. Changing one will automatically update the calculated velocity.
Is the speed evaluation in Prihoda always accurate?
The calculations are exact and rounded for real-life use. However, the speed evaluation is provided as informative guidance only.
What devices does Prihoda support?
Prihoda is available for iPhone, iPad, and iPod devices. It is designed to run on Apple's mobile operating system.
How often is Prihoda updated?
The latest version, 1.2, was released on September 30, 2017. The app was initially released on September 11, 2016.
Does Prihoda have ads?
No, Prihoda does not contain advertisements. It is a free application without any in-app purchases or ads.
What is the age rating for Prihoda?
