    Number of rows for cooling coil



    Kindly advise whether this equation is correct.

    Number of row=Btu/hr/(overall coefficient of coil x Log mean temperature different x face area x outside to inside ratio)

    Re: Number of rows for cooling coil

    Coil design is best left to reputable coil manufacturers. Give them you design air on and air off required conditions.
    Too many variables to re-invent the wheel, coil effective surface area, air dwell time, fin spacing standard or progressive, face velocities, air side pressure differential, filters fitted, induced air flow or forced air flow. DX of water chilled, integrated or full face feed. The options are endless.
    No short answer to your question.
