For fluid flow in pipes, friction is described by a dimensionless number, the fanning friction factor f. the fanning friction factor is dependent on number of parameters related to the size of the pipe and the fluid properties, which can all be represented by another dimensionless quantity, the reynolds number re. a formula that predicts f given re is the von karman equation: vi = 4 log10 (rev1) - 0.4 typical values for the reynolds number for turbulent flow are 10,000 to 500,000 and for the fanning friction factor are 0.001 to 0.01. (a) write a m-file to evaluate f given a user supplied value of re using bisection method. (b) plot f versus re for reynolds number ranging from 10,000 to 500,000. make sure the axis are properly labeled.

If you want to create an electrical current, which situation would produce a solution capable of this

A3.37-mg sample of protein was chemically digested to convert its nitrogen into ammonia and then diluted to 100.0 ml. then 10.0 ml of this solution was placed in a 50-ml volumetric flask and treated with 5 ml of phenol solution plus 2 ml of sodium hypochlorite solution. the sample was diluted to 50.0 ml, and the absorbance at 625 nm was measured in a 1.00-cm cuvette and found to be 0.486. for reference, a standard solution was prepared from 10.0 mg of nh4cl (molar mass = 53.49 grams/mole) dissolved in 1.00 l of water. then 10.0 ml of this standard was placed in a 50-ml volumetric flask, treated in the same manner as the unknown, and the absorbance found to be 0.323. finally, a reagent blank was prepared using distilled water in place of unknown, it was treated in the same manner as the unknown, and the absorbance found to be 0.076. calculate the weight percent of nitrogen in the protein.
