11. A constant pressure of 10 Pa is applied to a 1 kg parcel of dry air with initial tem- perature of 10°C. Determine the work done by the environmental pressure if the vol- ume of the parcel is reduced to 0.75 m3.

Final answer in three decimals. Show the solution.

[1] Repeat Example 7.10 (pages 288-289) but with the following exceptions: water is discharged at 9,000 kPa, and n=0.8. Calculate the work of the pump and AT using steam tables and equation 7.25

Select all statements that apply to constant volume calorimetry.     A coffee cup calorimeter is used.     A bomb calorimeter is used.     The system is the reaction or process.     The system is the water plus the calorimeter.     The surroundings include the reaction or process only.     The surroundings include the water plus the calorimeter.     The temperature of the water will always increase.     The temperature of the water will always decrease.     The temperature of the water could increase or decrease.     It is used to measure heat of combustion.     It is used to measure heat of solution or reaction.

If there are no constraints, how would you conduct a stage-wise distillation column so as to bring its efficiency closer to unity?

It proposes values for plotting the 6 different viscosity models (Dilatant, Newtonian, Psudoplastic, Plastic Bingham, Psudoplastic Bingham, Dilatant Bingham), all with the help of the formula:All this with the help of matlab. I need help plz i don't realy now how to use this.

Final answer in two decimals. Show the solution.

Chemical Engineering Make a preliminary design for a separator to separate a mixture of steam and water;flow-rates: steam 2000 kg/h, water 1000 kg/h; operating pressure 4 bar.
