Use this it for quick gas density calculation based on the molecular weight, temperature, pressure and z factor for the gas. Connecting the alarm of a mini condensate pump is a simple and essential step. It is commonly measured in feet per minute (ft/min) or meters per minute (m/min). All central air conditioners, for example, require ductwork with the specified size of ducts and airflow (measured in CFM). This formula assumes uniform flow conditions within the entire cross-sectional area, without any friction losses near to surfaces. For example, if a furnace has a listed input rating of 90,000 Btu's and an efficiency rating of 80%, it will produce 90,000 Btu input X .80 efficiency 72,000 Btu actual output Application of Data Generally the distance to the liquid level in an oil well is determined by generating a pressure wave in the casing annulus gas at the surface. Velocity gas hourly space To manufacture the lower aLkylamines by Method 1, ammonia and alcohol are passed continuously over a fixed bed containing the catalyst in a gas—soHd heterogeneous reaction.The ammonia to alcohol mole ratio varies from 2 1 to 6 1 depending on the amine desired as shown in Figure 1.
