To derive the design hour volume, the engineer multiplies the average annual daily traffic (AADT) by the K factor. A K factor is a ratio between a peak hour and the ADT.
An ADT value of 17140 for the SR 157, and a K-factor of 0.093 were obtained...
Question 6 (Peak Hour Factor): Given the traffic volume data provided below, answer the following questions: (1) Find the peak hour factor (PHF) for the hour of 4:00-5:00PM. (2) Find the peak hour factor (PHF) for the hour of 5:00-6:00PM. (3) Compare the two PHF values you got from part (1) and part (2). Which hour has a lower PHF value? What contributes to the lower value? (4) Based on your analysis, interpret the meaning of PHF. Time Interval 15-minute...

An experimental plot of In(k) vs. 1/T is obtained in lab for a reaction. The slope of the best-fit line for the graph is -3880 K. What is the value of the activation energy for the reaction in kJ/mol? The reaction A + 2B + C Products has a rate law of Rate = k[A]][B]. By what factor would the reaction rate change if [B] is tripled? What is the rate for the second order reaction A - Products when...
