At 8:00 A. M, there are 10 vehicles in a queue at a toll booth and vehicles are arriving at a rate of A0) -69-0.2t Beginning at 8 A. M. vehicles are being serviced at a rate ofμ 2.1 +0.3t A)and μ(t) are in vehicles per minute and t is in minutes after 8:00 A. M.]. Assuming D/D/1 queuing, what is the maximum queue length, and what would the total delay be from 8:00 A. M. until the queue clears? Draw D/D/1 queuing and queue length diagrams and label accordingly.

Which of the following is an easy way to remember the modified “x” tire rotation? a. nondrive wheels straight, cross the drive wheels b. drive wheels straight, cross the nondrive wheels c. drive wheels crossed, nondrive wheels straight d. drive wheels crossed, nondrive wheels crossed

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
