To determine air velocity changes, it is proposed to measure the electric current required to maintain a platinum wire of 0.5-mm diameter at a constant temperature of 77 C in a stream of air at 27 C. (a) Assuming Reynolds numbers in the range 40 ReD 1000, develop a relationship between the wire current and the velocity of the air that is in cross flow over the wire. Use this result to establish a relation between fractional changes in the current, I/I, and the air velocity, V/V. (b) Calculate the current required when the air velocity is 10 m/s and the electrical resistivity of the platinum wire is 17.1 105 m.

Day 10Binary Base ten numbers are decimal numbers Binary numbers are base 10 (only 1 and 0, on or off.) every binary has a unique decimal value and vice versa decimal numbers only have digits from 09, and they don’t have to have a decimal in them (ex.33, 493, 39393) example, how to get the decimal number 15 is (1x10^1)+(5x10^0) the value of a binary number and decimal number are different. If you see a number of only ones or zeroes, you have to be told whether it is decimal or binary check the lecture slides for this day Day 11 a breakpoint is a red point that stops to check what is happening the for loop is used when you want the calculations to be performed a certain number of times the first statement is how many times the statement will be executed
