I have a pipe 20 feet long. At one end (say A) its diameter is 10 feet and other end (say B) the diameter is 1 feet. Now, from A air is comming at 10 Km/Hour speed, what will be the speed of air when it will come out from B...
-
Just use the equation,
A1V1 = A2V2
Here
A1 is the cross-section area of the end A
A2 is the cross-section area of the end B
V1 is the speed of the air at end A = 10km/hour
V2 is the speed of the air at end B.
Don't forget to convert the feet into meter.
A1V1 = A2V2
Here
A1 is the cross-section area of the end A
A2 is the cross-section area of the end B
V1 is the speed of the air at end A = 10km/hour
V2 is the speed of the air at end B.
