Determine the share (proportion) of person-trips by each of two modes
(private auto and mass transit) using the
multinomial logit model and given the following information:
Utility function: Uk = Ak - 0.05 Ta - 0.04 Tw - 0.03 Tr - 0.014 C
Parameter Private Auto Bus
Ta = access time (min.) 5 10
Tw = waiting time (min.) 0 15
Tr = riding time (min.) 25 40
C = out-of-pocket cost (cents) 150 100
Calibration constant, Ak 0.01 0.07

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
