PLEASE leave feedback and/or requests in the guestbook or send an email. Line D represents a system impedance within a given designed system. To help you understand BTU, it helps to break down this equation into simpler terms. The volumetric flow rate of a liquid or gas in cubic feet per minute. So, a range that is capable of producing 35,000 BTUs should be paired with a range hood with a rating of 350 CFM or greater. 0 The BTU designation is one of the most important considerations when selecting a portable A/C unit. com provides an online conversion calculator for all types of measurement units. 1 cubic foot = 1,037 Btu (based on U. 003 ft when straight and fully stretched tight at 0% compression (adjusted at other compressions), otherwise the original method of constant 0. Once you have the system airflow and the temperature change through the system, you can calculate the BTUs the system is delivering into the building. = 1/(t1-t0) · ∫p (t)dt. System Enthalpy: 30 - 21. air) Latent Heat (BTU/hr) = 0. Cfm To Btu. Natural gas is measured in therms or BTUs. A typical window air conditioner might be rated at 10,000 Btu. The saturated steam is by definition 212°F or 100°C at 1 atmosphere. Use this calculator to convert mass flow rate and density of a substance to the rate of volumetric flow. To simply convert from any unit into W, for example, from 50 BTU/h, just multiply by the value in the right column in the table below. 3 - gpm = 15. We couldn't find a conversion between cfm and btu [incompatible types] Do a quick conversion: 1 cubic feet/minute = Btus using the online calculator for metric conversions. 1 BTU per hour to Atmosphere-cubic feet per minute (BTU IT /h to atm cfm) conversion calculator of Power measurement, 1 BTU per hour = 0. However, calculating BTU is not an impossible task, and you can even do it all by yourself. For air conditioners, there is a BTU-to-room sizing rule of thumb. Therefore, Total BTUs = 4500+1000 = 5500. Choosing an undersized unit will overwork the unit and it will not cool properly. Divide that result by 60 to devise the gas transfer rate in cubic feet per minute. Using standard conversion equations (Watts x 3. 50 BTU/h * 0. 40395 psia·ft3 Btu 2. To help future furnace owners out, we have developed a simple furnace sizing calculator. 1868 kJ / kg·K Btu / lbm·°F 4.
