10.19 Estimate the fugacity of one of the following: (a) Cyclopentane at 110°C and 275 bar. At 110°C the vapor pressure of cyclopentane is 5.267 bar. (b) 1-Butene at 120°C and 34 bar. At 120°C the vapor pressure of 1-butene is 25.83 bar.

Solve the following problem and show your complete solutions for better understanding

In a certain manufacturing process a certain Liquid gas under 14.7 psia pressure with has a normal boiling point of -183 °C. They decided to be store this in a spherical container with 11.811 inches OD. The system is kept adiabatic by enclosing the container inside another concentric sphere of 0.45 m ID, with intervening space evacuated. Both the sphere surfaces are made of aluminum with e= 0.3. The temperature of the outer sphere is 40°C. To miminized heat gain a polished aluminum with an emissivity of 0.03 was used for container walls. Determine the percentage reduction.choices 81,90% 10.67% 83.12% 39,68% 78.56% 89.75%

plz answer both 2 questions

At about what pressure would the mean free path of an air molecule at room temperature equal 10 em, the size of a typical laboratory apparatus?

Answer is

1. Calculate the pressure difference AP=Pg-Pa of the below manometer. Glycerin SG = 1.26 Water SG = 1.0 Oil SG = 0.88 60 cm 10 cm B 15 cm 20 cm Mercury SG = 13.5
