A radiator has a cooling pipe of diameter 40 mm and negligible thickness. Fins are attached on the outer surface of the pipe in order to increase the heat transfer surface area on the air side. The heat transfer coefficient on inner and outer surfaces are 2000 W/m2K and 150 W/m2K respectively. If the effective surface area on the finned side is 12 times the inner surface area, the overall heat transfer coefficient of this heat exchanger based on inside surface area (in W/m2K) is_________.
    Correct answer is '947.37'. Can you explain this answer?

    Given hi= 2000 W/m2K
    ho = 150 W/m2K
    Ai = inside surface area
    Ao = outside surface area = 12Ai
    1/ui = 0.0005 + 5.556 x 10-4
    ⇒ ui = 947.37 W/m2K
