Ductwork specific pressure loss calculation. In systems with vacuum pumps, blowers, compressors, and heat exchangers, air pressure and temperature are constantly changing, which means the actual volume flow is changing. The answer is: 1 m3/sec equals 1,000.00 kg/sec 1,000.00 kg/sec is converted to 1 of what? Air velocity (distance traveled per unit of time) is usually expressed in Linear Feet per Minute (LFM). For scientific, educational and general purposes to convert from one unit to another. Volume flow is usually measured in Cubic Feet per Minute (CFM). It will decrease with increasing temperature, the lower pressure at your altitude (which varies with weather), and with humidity (moist air has lower density). Even at 40 °C, your air density will be slightly over 1 kg/m³, Copyright ©1997-20014, OnlineConversion.com. For science and education. Dry air at 101.325 kPa, 0 °C is about 1.29 kg/m³. Mass air-flow rate unit converter. By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Hi there, do you mean 300m inland, or 300m above sea level? Let's say the air temperature is 12.8 to 40 celcius, and location of 300m from sea level. The answer is: 1 m3/h equals 0.28 kg/sec 0.28 kg/sec is converted to 1 of what? Dry air at 101.325 kPa, 0 °C is about 1.29 kg/m³. We are working on allowing guests to post, sorry for the trouble. The kilograms (water mass) per second unit number 0.28 kg/sec converts to 1 m3/h, one cubic meter per hour. And 12, Density of air varies with temperature, pressure, and humidity. For incompressible flows, the mass flow rate is constant. Welcome to the OnlineConversion.com forums. Density of air varies with temperature, pressure, and humidity. Due to changes in this version of the forum software, you are now required to register before you may post. This page was generated at 10:28 AM. It will decrease with increasing temperature, the lower pressure at your altitude (which varies with weather), and with humidity (moist air has lower density). kg/hr: Volume (English) CFM ft ASL PSIA °F PSIG: Volume (Metric) M3/hr m ASL BarA °C BarG . Converter provides units and measures conversions. Calculation of moist air properties. It is the EQUAL flow rate value of 1 cubic meter per hour but in the kilograms … You should consult an air density table or graph. So assuming you have an area of 1 m^2 with a velocity of 1 m/s, air with a density of 1.225 kg/m^3 will equate to a mass flow of 1.225 kg/s. The kilograms (water mass) per second unit number 1,000.00 kg/sec converts to 1 m3/sec, one cubic meter per second. (Hence mass flow is equal to density times area times velocity. Air-handling plant area calculation. Thermal insulation and ductwork heat loss calculation. All times are GMT-8. Is 1 cubic meter per second of air flow rate equivalent to 1 kg/s ? h-x diagram. It is the EQUAL flow rate value of 1 cubic meter per second but in the kilograms (water mass) per second flow rate unit alternative. You should consult an air density table or … Air-handling ductwork cross-section design.
