For any math nerds out there, I was demonstrating to an apprentice the massive difference larger diameter hoses make when evacuating. Yes, I realize the math is based on using the diameter as the radius, but the point is that the area of the hose increases exponentially as you increase the diameter. This is why 1/2” or 3/4” hoses are the best for evacuations. 🤓
