Air with a dry-bulb temperature of 38oC and a wet-bulb temperature of 27oC is scrubbed with water to remove dust. Water temperature is maintained at 25oC. The air leaving the scrubber is in equilibrium with water. It is then heated to 93oC in an air preheater and admitted to an adiabatic rotary drier. The air leaves the drier at 49oC. The material losses moisture at a rate of 0.05 kg of water per kg of product. The total product is 1000 kg/h.

during the beer brewing process the wort (solution containing sugars extracted from grain) is boiled to sterilize and precipitate proteins. This solution is then cooled before adding yeast to allow fermentation. One way to speed the cooling process is to place the brew kettle in ice. How much energy is lost if 1.00 kg of ice (0.0 ̊C) is used to cool the kettle, all the ice melts, and the ending temperature of both the water and kettle have a final temperature of 20. ̊C. The enthalpy of fusion of water is 6.02 kJ/mol. The specific heat of water is 4.184 J/g ̊C.

This was a lab I performed where we mix aqueous 25ml HCl and 25ml NaOH and use a program called microlab to determine the cooling rate after the initial heating. We used a coffee cup calorimeter that had a stirring bar. At first, NaOH solution is by itself in the coffee cup calorimeter. It’s temperature was 23.02 C. I waited for 70 seconds and then added the 25ml of HCl to it. The temperature rose to 29.59 C, then began to cool down immediately. The cooling rate was y=0.0089x+26.1273 according to the program. The final weight of the solution was 47.147g. The moles of NaOH was 0.919M and HCl was 1.033M. The questions: calculate the theoretical value for change in delta Hrxn.
A hydrocarbon stream composed of 40 mol% n-butane and 60 mol% n-octane is fed at 100 kmol/h to a flash vessel operating at 5 bar and 145°C. The liquid outlet stream of the flash vessel is then sent to a distillation column with a partial condenser to further separate the components. 90% of the butane in the feed to the column is recovered in the overhead vapor product (distillate), along with small amounts of octane. The bottoms product contains octane which accounts for 75% of the octane in the fresh hydrocarbon feed (to the flash vessel). The condenser and reboiler operating temperatures are 136.7°C and 165.7°C, respectively. Determine the compositions of the liquid outlet stream of the condenser and the vapor outlet stream of the reboiler.
Please I need help. Be as detailed as possible. Thank you! An ideal gas is placed in a cylinder with a movable heavy piston. The gas inside the cylinder has an initial pressure of 1.2 x 105 N/m2 , an initial temperature of 280 K, and an initial volume of 1 x 10-3 m3. A stove underneath the cylinder transfer energy to the gas through heating, causing the volume of the gas to increase to 2 x 10-3 m3. Assume that the gas expands isobarically (at constant pressure). 1) Draw a qualitative energy bar chart showing the changes of the energy within the system.
