Question

The length of pipe is 1km and its diameter is 20cm if the diameter of an equivakent pipe is 40cm then its length is

Answer 1

Answer:

Length is 1st pipe(l1)=1Km

Diameter(d1)=20cm

Diameter of 2nd pipe(d2)=40 cm

Let the length (l2)=x

Step-by-step explanation:

Since both pipes are equivalent, we have

l1×d1=l2×d2

Or,1×20=x×40

Or,20=40x

Therefore,x=20/40=(1/2)km=500m
