A system has been devised to store acetonitrile safely at high pressures and temperatures. The acetonitrile is contained in a 0.2-ft3 tank maintained at 4500psia and 550°F. This tank is placed inside a second tank whose volume, excluding the volume of the first tank, is 2 ft3. Nitrogen at 10.0 atm and 550°F is contained in the second tank. Use the compressibility chart to estimate the final system pressure (atm) if the first tank ruptures and the final system temperature is 550°F. The critical temperature and pressure of acetonitrile are 548 K and 47.7 atm, respectively.
For networks in which the magnitude of the resistive elements is typically in kilohms, is the approximation of Fig. 3.10c a valid one [based on the results of part (a)]?
Estimate the heat-transfer coefficient for steam condensing on the outside, and on the inside, of a 25 mm o.d., 21 mm i.d. vertical tube 3.66 m long. The steam condensate rate is 0.015 kg/s per tube and condensation takes place at 3 bar. The steam..

Acetone is to be extracted from a solution in water, using 1,1,2-trichloroethane. The feed concentration is 45.0% w/w acetone. Determine the number of stages required to reduce the concentration of acetone to below 10%, using 32 kg of extraction-s..
1. In this problem, you learn how to apply the energy balance to a closed system containing an ideal gas with constant Cpfor 3 different processes.
is to be separated in a reversible continuous flow isothermal, isobaric separator into pure acetone and an aeotrope that forms at 39.250C under atmospheric pressure. The azeotrope contains 61mole % CS2.
The left side of of the mechanical energy equation has three terms: P/p, (1/2)av^2 and gz. show that each of these terms has the dimension of energy per mass of fluid by.... a) converting each term to units of Btu/lbm beginning with pressure in psi, ..
The unit is to operate 8000 h/year. Determine the height and diameter of the absorption tower at conditions of minimum annual cost.
Experimental tests have been carried out on this equipment, and the results for the slurry mixture used can be expressed as follows for any one pressure drop:
List two reasons why water is seldom used as a solvent in sample preparation for infrared spectroscopy.
A solution with composition x1 = 0.2 is to be stored at 250 K. It is important to avoid the formation of vapor. What is the minimum pressure required?
where V is the molar volume at temperature T, and a is a constant. Initially one mole of the gas is at temperature T1 and occupies volume V1. The gas is allowed to expand adiabatically into a vacuum so that it occupies a total volume V2.
