Air at 90°C and 1.00 atm (absolute) contains 10.0 mole% water. A continuous stream of this air enters a compressor-condenser, in which the temperature is lowered to 15.6°C and the pressure is raised to 3.00 atm. The air leaving the condenser is then heated isobarically to 100°C. Calculate the fraction of water that is condensed from the air, the relative humidity of the air at 100°C, and the ratio m3 outlet air at 100°C/m3 feed air at 90°C.
b. A 12.6-g sample of acetylene, C2H2, produced a temperature increase of 16.9C in the same calorimeter. What is the energy of combustion of acetylene (in kJ/mol)?
Neglecting field-current changes, armature reaction, and armature inductance, find the initial and final values of the armature current and speed corresponding to each step.
Take the natural gas to be an ideal-gas mixture with temperature-dependent heat capacities for each component given in Perry's Handbook. Is the ideal-gas assumption reasonable?
Implement a traffic light controller FSM with a state encoding where GNS=00, YNS = 01, GEW = 10, and YEW = 11. Show Karnaugh maps for the next state variables and output variables and a gate level schematic for the FSM.
The gas flow rate is 4000 kg/hr.sqm of air and the water entering is 6250 kg/hr.sqm. 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. Ho..
Determine the fraction of load for which the efficiency is a maximum, and calculate the corresponding efficiencies for the power factors of unity, 0.8, and 0.6.
The pressure is 1 bar, the relative humidity is 75%, and the dew temperature is 25 °C. What is the mol fraction of water vapor in the air?
If the capital costs in the adipic acid example described in Example 9.5 are known to within -10% to +30%, and the cash flow from operations is predicted within ±10%, estimate the mean and standard deviation of the 10-year NPV. Is there a greater ..
-12 the gravimetric composition and properties of two different typical fuels i.e. coal and fuel oil is tabulated below- Parameters coal fuel oil Composition weight% -- C 76 85 H 4.5 11.5 S 0.5 3.5 N 1.0 -- O 3.0
a discuss how the phase equilibria of mixtures are represented using diagrams similar to the pressure-temperature and
Two wires both carry the same current (I). The moving charged particles in both wires are electrons, but the concentration of moving electrons in wire #1 is double the concentration of moving electrons in wire #2.
Compute the sending-end voltage, current, real power, and reactive power for the following conditions:
