The answer is minus 1.26 KJ/mol for H(3). Demonstrate the reference state to the process state and calculations. I only need help for determing that variable.
Exhaust gas from a power plant passes through a 15-by-20-it rectangular duct at an average velocity of 50 ft/s. The total length of duct is 250 ft and there are two 90° bends.The gas is at 180°F and about 1 atm, and the properties are similar to those of air. Calculate the pressure drop in the duet and the power required to overcome pressure losses.
Untuk sistem gas etilena (1)/propilena (2), estimasi (f^1, f^2, $^1, dan ^2 pada t = 150°C, P = 30 bar, dan y1 = 0,35; kij = 0. (a) Dengan menerapkan Persamaan (10.63). (b) Dengan asumsi bahwa campuran adalah lingkungan ideal

The resin has a diameter of 100 μm and a void fraction of 0.3, and your mobile phase flows through the column at a rate of Q = 5 cm³/min. The Van Deemter coefficients A, B, and C have been determined to be 0.0228 cm, 0.0036 cm²/min, and 0.00053 min, respectively, for both proteins. Protein A elutes from the column with an average retention time of 27 min and standard deviation of 0.8 min. Protein B elutes from the column. with an average retention time of 33.8 min and standard deviation of 1.0. a) How many theoretical plates does the column contain? b) What flow rate (Q) will give you the maximum resolution? c) What is the minimum height of a theoretical plate for the system?arrow_forward
