Problem 10.8: The following table is a set of VLE data for methanol(1)/water(2) at 333.15 K.
a) What is the saturation pressure of methanol at 333.15 K? b) What is the phase of the mixture that contains 50% (by mole) methanol at 333.15 K and 40 kPa? c) At z1 = 0.2 and 30 kPa, the system is present as two phases. What is the chemical potential of methanol and water in the vapor phase using an ideal gas reference state at 300 K and 101 kPa? Is the assumption of treating the vapor phase as an ideal gas
A plating waste with a flow of 50 L/min contains 274 mg/L of NaCN. Determine the amounts of chlorine as Ca(OCl)2 and NaOH required to: (a) Oxidize the cyanide to cyanide; and (b) Oxidize the cyanide to CO2 and H2O.
The molar specific heat of many materials at low temperatures is found to obey the Debye law C_v = A[T/theta]^3 where A is a constant equal to 1.94 x 10^3 Jmol^-1K^-1 and with the Debye temperature theta taking different values for different mater..
Two balanced, three-phase, wye-connected loads are in parallel across a balanced three-phase supply. Load 1 draws a current of 20 A at 0.8 power factor leading, and load 2 draws a current of 30 A at 0.8 power factor lagging.
In a wood chemistry/wood physics lab, we were asked to place a piece of wood that contained approx. 64% moisture content in a hydraulic press where we applied a constant 400 psi pressure and applied a constant 400 degrees F of heat. We inserted a ..
One compartment is evacuated, the other contains steam at 7.5 bar, 300 °C. The latches are removed and the gas expands to fill the entire volume of the cylinder. When the system reaches equilibrium, its pressure is 1 bar. Determine the final tempe..

An insulated cylinder fitted with a weightless latched piston contains steam at 5 bar, 300 °C. The piston is unlatched and the steam expands against ambient air at P = 1 bar. The temperature of steam in the final state is 142 °C. Determine the ene..
Safety considerations require that the maximum steady-state temperature of the system remain below 475°C. Will a spherical container with inner and outer diameters of 1.0 m and 1.2 m, respectively, satisfy this requirement?
