Sometimes, you will bump into the word entropy, and I wanted to take a stab at making it more understandable. We assume you are converting between water column [centimeter] and inch of water [4 C]. This process is automatic. The trouble was that we needed data-logging capability AND accurate measurement at 600+ amps. That means that for a manometer or Magnehelic to be properly used, you MUST recalibrate them before each use (many auto-calibrate to zero) to compensate for changes in elevation and barometric pressure. What is the pressure (psi) drop per 100 ft length of pipe and the flow velocity? Use this page to learn how to convert between water column and inches of water. But perhaps a more relevant description of BTUs for a fire pit or outdoor decorative appliance is that the greater the BTU the more flame and the more heat the fire pit or appliance will generate. Manual J calculations must consider non-design days, not just the design conditions, including partial load conditions. Example: 10 in. Below is the breakdown.
