A compressor is being used to adiabatically compress 5 mol/s of ammonia. The ammonia comes into the compressor at 100C and 10bar, then exits at 150C and 25bar. How much work is required for this process? Assume that ammonia is an ideal gas with a constant Cv of 30 J/mol*K.
For this system, Henry's law holds good and y = 1.75 x, where y is the mole fraction of acetone in the gas in equilibrium with a mole fraction x in the liquid. How many overall transfer units are required?
List as many items and give as many details as possible. Hints: Consider the problems of obstacle detection, information display, propulsion system, inertial guidance, route recall, power supply, etc.
Suppose that the adsorbate equation of state is given by z = 1 +ßn, where ß is a function of T only. Find the implied adsorption isotherm, and show under what conditions it reduces to the Langmuir isotherm.
.At time zero, the valve is opened; at time t, the valve is closed, and the bulkcontents are analyzed. Explain how this information can be used to calculate thediffusion coefficient in this binary gas mixture.
Determine the power output of the turbine and the efficiency of its operation in comparison with a turbine that operates reversibly and adiabatically from the same initial conditions to the same final pressure.
