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.

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
