Example 2.3: Determining the Phase
Based only on the Antoine equation given in Example 2.2, determine the phase of water at
(a) 2 bar, 115 °C, and
(b) 20 bar, 300 °C.
Example 2.5:
Locating the State in the Steam Tables
A 12m3 pressurized vessel contains 200 kg of steam at 40 bar. What is the temperature?
Example 2.11:
Solving Cubic Equations for the Volume
Use the van der Waals, the Soave-Redlich-Kwong, and the Peng-Robinson equations to determine the molar volumes of the saturated phases of ethylene at 260 K (the saturation pressure is 30.35 bar). Compare with the tabulated values,VL = 0.0713 l/mol, VV = 0.456 l/mol.
What is fugacity? How does it relate the chemical properties of ideal gases to real gasses and what is the equation for it?
Find the components of the convective momentum flux pvv inside and outside the slot - Evaluate the xx-component of pvv.
Determine the motor current and speed when the diverter-circuit resistance is made equal to the series-field resistance. Neglect saturation and the voltage drops across the series- field resistance as well as the armature resistance.
HEAT TRANSFER PROBLEM NO18 - The configuration of a furnace can be approximate as an equilibrium triangular duct which is usually long enough so that the end effects are negligible , the hot wall is maintained at 900 k and has an emissivity e1 = 0..
The ammonia mixture enters the tower enters the tower at a rate of 1000 ft3/min measured as dry gas at 60 oF and 1 atm. the pressure of both streams and throughout the tower = 15 lbf /in2 g. what percentage of the ammonia entering the tower is not ..
Draw the graph carefully. Please use one graph per country and show both the autarkyand the free trade equilibrium on each graph.
Prepare a PowerPoint presentation to provide an argument for or against the use of glass over PET/PEN for small-pack beer packaging.
Mass transfer coefficient from a free water surface to an adjacent moving air stream has been found to be 0.015 kg/m2-s. Estimate the rate of evaporation from a surface of 1 m2 at a temperature of 28 oc into an air..
A loaded semi-truck consumes about 10 US gallons of diesel per hour (assuming an average speed of 60 mph) and is driven about 16 hours per day, every day of the year. The density of diesel id 0.85 kg/liter. If 1 barrel of crude oil produces 10..
The physical properties of the fluid are: density 875 kg/m3, viscosity 1.46 mN m-2 s. Also, determine the NPSH, at this flow rate, if the vapor pressure of the fluid at the pump suction is 25 kN/m2.
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.
Forty-five kilograms of a solution containing 30 wt% ethylene glycol in water is to be extracted with furfural. Using Figures 4.14a and 4.14c, calculate:
