An engineer claims she has invented a system that operates according to the ideal ra cycle with maximum and minimum temperatures (associated with warm surface wat versus colder deep water) equal to th = 26.85°c and tc = 1.85°c. the cycle is saic have a net output of shaft power wnet = 50 kw, and a working fluid flow rate of ri 0.25 kg/s of (pure, non-ocean) water. assume the maximum temperature occurs a saturated vapor conditions and the minimum temperature occurs at saturated liquid conditions. does the invention violate the 2nd law of thermodynamics? show worl no. the net shaft power is slightly lower than the ideal (maximum poss: shaft power (wnet. ideal = 51.9 kw) under the given conditions.

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.

When you mate two plants together the terms is called? answer it fast as possible plz! i have a test tomorrow!

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
