Under standard pressure and temperature

During this laboratory experiment, recorded volumetric flow rates were displayed in Standard Liters Per Minute (SLPM) and Standard Cubic Feet per Hour (Scfh). Since this experiment did not actually operated under standard pressure and temperature, these gas flow rates had to be converted to experimental Liters Per Minute (LPM) and cubic feet per hour (cfh). The following equation was used to make both of these conversations: FSLPM FLPM 273 Tgas § © ¨¨ · ¹ ¸¸ Pgas 14.7 § ©¨ · ¹¸ (1) Solving for F(LPM): (2) Where and were experimentally recorded temperatures and pressure all converted into SI Unites (Degrees Kelvin and kilopascals). The same exact operation was performed to convert Scfh to Cfh. FLPM FSLPM Tgas 273 § ©¨ · ¹¸14.7 Pgas § © ¨¨ · ¹ ¸¸ Tgas Following this, the determined experimental gas flow rates were converted To SI Units (lits/min and ft3 /hr) to ( /sec) by finding the conversion factor between the two through the dimensional analysis shown below. For the inlet and cold streams: (3) v Flow Rate in m3 sec (4) and for the hot stream: 1ft 3 hr § ©¨ · ¹¸ 1m 3 35.3 ft 3 § ©¨ · ¹¸ 1hr 60min § ©¨ · ¹¸ 1min 60sec § ©¨ · ¹¸ 7.869x106 m 3 sec (5) v Ý , Flow Rate in m3 sec (6) For the purposes of this experiment the air flows in the all streams were considered to be ideal gases. This allowed for the calculate mass flow rates for the stream for using the Ideal gas equation: Pv mRT (7) and solving for mass flow rate m , RT Pv m (8) where R is the air gas constant (0.287kj/kg-K). The enthalpy values for the streams were also calculating using an Ideal gas equation: h c p xT (9) where c p is the specific heat of air (1.009kj/
