The primary function is to induce protection against viruses in neighboring, non-infected cells. In the target cells they cause digestion of viral DNA and viral proteins.
Step 1. Find the streams width
Step 2. Find the average velocity of the stream
Step 3. Calculate the streams discharge (Multiply the cross-sectional area (Feet)² from Step 1 by the corrected average stream velocity (Feet/Second) from Step 2.)
Those are the step on how to do it
