A rigid vessel contains 0.014 m3 of saturated-vapor steam in equilibrium with 0.021 m3 of saturated-liquid water at 373.15 K (100°C). Heat is transferred to the vessel until one phase just disappears, and a single phase remains. Which phase (liquid or vapor) remains, and what are its temperature and pressure? How much heat is transferred in the process?
Hydrogen gives off 120. J/g of energy when burned in oxygen, and methane gives off 50. J/g under the same circumstances. If a mixture of 5.0 g of hydrogen and 10. g of methane is burned, and the heat released is transferred to 50.0 g of water at 2..
A condenser is required to condense n-propanol vapour leaving the top of adistillation column. The n-propanol is essentially pure, and is a saturated vapourat a pressure of 2.1 bara. The condensate needs to be sub-cooled to 45ŽC.Design a horizonta..
A turbine is fitted in the pipeline to recover the excess energy that is available, over that required to transfer the liquid from one vessel to the other. Estimate the power that can be taken from the turbine, when the liquid transfer rate is 500..
what is the Pareto efficient number of streetlights to provide? (HINT: you have to calculate social marginal value and put it equal to marginal cost).
A solution of the two components that contains 62% mol toluene is slowly heated at constant pressure. When the solution begins to boil the temperature reads 120 °C. What is the pressure?
Assume that the absorption coefficient is 0:1 cm-1, the scattering coefficient of a 5-cm thick tissue is 100 cm-1, the scattering anisotropy is 0.9, and the wavelength of light is 0:5 mm. Calculate the light fluence rate 5 cm from the source.
Suppose the volumetric flow rate of the gas leaving the condenser is 20.0m3/h Calculate the rate (kg/h) at which acetone is vaporized in the solvent recovery unit.
Do you expect that to be lower or higher than a constant temperature case of the same exposure duration?
For an ideal gas (this is an assumption that can be made under certain conditions including low pressure and high volume in which it is assumed that the molecules in a system either do not touch OR their collisions are completely elastic), the pressu..
Select a process variable (pressure / temperature / level / flow) and conduct a literature survey to determine recent developments in process instrumentation field. Identify any one novel instrument and explain in detail the working of the instrument..
a)Draw and label the flowchart and carry out the degree-of-freedom analysis using balances on atomic species.(b)Determine the molar flow of oxygen supplied to the boiler.
Determine the force applied to the plunger by the electric system.
