The pipe specification is φ219×6, and the medium flow rate is 600 cubic meters per hour; what is the flow velocity? How to calculate
First, calculate the cross-sectional area S, then use the flow rate Q; subsequently, V = Q/S

The flow rate is 600 cubic meters per hour; divided by 3600 seconds per hour, this equals 1/6 cubic meter per second. The inner diameter of the pipe is 219 – 6×2 = 207 mm, which is equivalent to 0.207 meters, while the radius is 0.1035 meters. The cross-sectional area of the pipe is 0.1035*0.1035*3.14 = 0.0336 square meters ； 1/6/0.0336=4.95 meters/second
φ219×6, where 219 represents the outer diameter of 219 MM, and 6 indicates a wall thickness of 6 MM; thus, the inner diameter of the tube is D=219-12=207 MM
It can be converted from the unit as well! m3/h—m/h or m/s, a problem related to the cross-sectional area within a pipe
