    EDR calculations

    Many buildings in NYC use the steam risers to heat the bathrooms and kitchens.
    When calculating the load for a boiler, how do you calculate the EDR for the risers. In my case they are 2 inch pipes, 30 feet in length.
    Thank you.

    Two inch pipe

    measures 7.46" in circumference, or 0.62177 square feet per lineal foot.  30 feet would have an EDR of 18.65 square feet.
