The area of flow is approximately 209.5 cm².
Given data :
Inner diameter of the given pipe is 20 centimetres.
Depth of flow = 1/3 × diameter of the given pipe.
• Now,to calculate the area of flow,we have to calculate the inner radius of the given pipe
= Diameter / 2
= 20/2
= 10 cm
• Now,we have to calculate the height of the flow
= 20×1/3
= 20/3 cm
• At last we have to calculate the area of flow by using the following mathematical formula :
= π × (radius of the pipe) × flow height
= π × 10 × 20/3
= 22/7 × 10 × 20/3
= 209.5 cm² (answer) (approximate)
