Six tanks of different constructional materials and six different materials to be stored in these tanks are listed in the following columns:
All tanks must be used, and all materials must be stored without using more than one tank for any one material. Indicate the material that should be stored in each tank.
Latest commercial technologies, R&D in visbreaking with potential areas still need for improvement
How much water and urea (the main waste product) pass into the dialysate if the entering concentration of urea is 2.30 mg/mL and the exit concentration of urea is 1.70mg/ mL? If the dialyzing fliud flows into the unit at the rate of 1500 mL/ min, wha..
Determine the values of the constants a and c and state the units and draw the path on a PV diagram also draw Path on the diagram and calculate the heat and work interchanges between the system and surroundings.
The estimated cost of the pipes, per unit length is: schedule 40 carbon steel $5, schedule 80 carbon steel $8.30, stainless steel (304) schedule 40 $24.80. Installation and fittings for all the materials adds $16.5 per unit length. The downtime re..
All other conditions are the same as those specified in Example 5 of this chapter, except that Bi is not given. 8. Present a detailed derivation of Eq. (481 in this chapter, using, as a starting point, any of the other equations that are given.
a. Develop a general equation that relates the average value of n to the mass of a given mixture of PCBs and the mass of AgCl produced. b. A 0.1947-g sample of a commercial PCB yielded 0.4791 g of AgCl. What is the average value of n for this samp..
Calculate the standard enthalpy of combustion per gram of liquid methanol and compare this answer to that for ethanol in Exercise 75.
The Soave-Redlich-Kwong equation is a commonly used cubic equation of state, second in popularity only to the Peng-Robinson Equation of state. In this problem, just derive the two equations (7.66) given in the problem.
Aqueous sulfuric solutions containing 15.0 wt% H2SO4 and 80.0 wt% H2SO4 are mixed to form a 30.0 wt% product solution. The 15 % solution was in a lab in which the temperature was 77 F. The 80% solution had just been taken from a storage cabinet in an..
Plot of the Fermi distribution function at two different temperatures. Calculate the Fermi timction at 6.5 eV if EF=6 .25 eV and T=300 K. Repeat for T=950 K assuming that the Fermi energy does not change. Plot the energy dependence of the ele..
