Calculation of specific gravity and viscosity of 15% KOH aqueous solution at different temperatures
Thread Content
As the title suggests: For work purposes, I need to know the specific gravity and viscosity of a 15% KOH aqueous solution at different temperatures (30, 40, 50). I tried to calculate this on my own for half a day without success; I was able to get the values using an electrolyte calculator, but the results were incorrect. I seek advice from the experts.
What data do you use for comparison?
Only the specific gravity was checked; there are no data on viscosity. It matches the data found online, but the difference is quite large.
Temperature: 30.0000; Viscosity, absolute: 1.15931 cP; Density: 1.13183 g/ml
Temperature: 40.0000; Viscosity, absolute: 0.974311 cP; Density: 1.12475 g/ml
Temperature: 50.0000; Viscosity, absolute: 0.833356 cP; Density: 1.11788 g/ml
How did the teacher calculate it? Could you give some guidance?
The results I obtained using ProII don’t seem correct. Phase: Liquid; Total Stream; Standard Liquid Flow Rate: 0.1025812305 M3/HR; Temperature: 40°C; Pressure: 3 KG/CM2; Molecular Weight: 23.72883387; Enthalpy: -0.3888910141 M*KCAL/HR; KCAL/KG: -3161.715561; Mole Fraction of Liquid: 1; Reduced Temperature: 0.3318460385; Reduced Pressure: n/a; Acentric Factor: n/a; UOP K Factor: 8.324058679; Standard Liquid Density: 1199.049761 KG/M3; Specific Gravity: 1.200233191; API Gravity: -13.60624317; Liquid Molecular Weight: 23.72883387; Z (from K): n/a; Enthalpy: -3161.715561 KCAL/KG; CP: 0.5568526077 KCAL/KG·C; Density: 1331.773538 KG/M3; Surface Tension: n/a DYNE/CM; Thermal Conductivity: n/a KCAL/HR·M·C; Viscosity: n/a
Okay, I made a mistake myself. Thank you, teacher!
