Looking online, I found that the inside diameter of a 1'' schedule 40 pipe is 1.049''

Radius = 0.5245''

Area of pipe opening = 0.8642529244 sq inches = 5.575814167 sq cm

Distance water travels through pipe in 1 minute

= Volume of water flowing out in 1 minute / Area of pipe opening

= 30 L / (5.575814167 sq cm)

= 53.8 m

So water flows at a rate of 53.8 meters/min
