Calculate the pipe diameter for a hydronic heating system

What is the pipe diameter required for a hydronic heating system serving an area with a total heat loss of 500,000 BTU/Hour and a temperature differential of 25°F?

What formula can be used to determine the pipe diameter for a hydronic heating system?

Pipe Diameter Calculation:

The pipe diameter required for a hydronic heating system serving an area with a total heat loss of 500,000 BTU/Hour, a temperature differential of 25°F, and a piping Hazen-Williams coefficient, C = 130, can be calculated using the Darcy-Weisbach equation and Reynolds number formula.

Given the total heat loss of 500,000 BTU/Hour, temperature differential of 25°F, and piping Hazen-Williams coefficient of C = 130, we can use the Darcy-Weisbach equation and Reynolds number formula to determine the pipe diameter needed for the hydronic heating system.

The Darcy-Weisbach equation is used to calculate the head loss in a pipe due to friction. By rearranging the formula and considering the Reynolds number at the average velocity, we can calculate the diameter of the pipe required for the system.

Therefore, the calculated pipe diameter required for the hydronic heating system serving an area with a total heat loss of 500,000 BTU/Hour, a temperature differential of 25°F, and a piping Hazen-Williams coefficient of C = 130 is approximately 1.377 inches (rounded to 1.25 inches).

Understanding the flow dynamics and heat loss calculations is crucial in determining the appropriate pipe diameter for efficient operation of a hydronic heating system.
