Question

In a hot water heating system, there is a cylindrical pipe of length 28 m and diameter 5 cm. Find the total radiating surface in the system.. IN THIS QUESTION WHY WE USE CURVED SURFACE AREA ? WHY NOT TOTAL SURFACE AREA

Answer 1

because there is a cylindrical pine and as it is pipe then the water will flow from it and to let the water flow it should be opened from top and bottom so we usre C.S.A instead of T.S.A.
