Queue at park vehicles arrive at an entrance to a recreational park. there is a single gate, where a park attendant distributes a free brochure. the park opens at 8: 00 a. m., at which time vehicles begin to arrive at an average rate of 180 veh/h (poisson distributed). assume it takes an average of 15 seconds to distribute brochures, but the distribution time varies depending on whether the park patrons have questions related to park operating policies or not. compute the: a. what is the average length of queue, not including the vehicle being served? b. estimate the average waiting time of a vehicle? c. what is the average total time spent in the queue? d. what is the probability that there are 3 or more vehicles at the queue? e. what is the probability of a vehicle spending more than 1.5 min in the queue?

![180^2/240(240 - 180) = 2.25 vehiclesSince vehicles must be a positive integer, hence ≈ 3 vehiclesB. Average waiting time of vehicle = average queue length / arrival rate= 2.25 / 180 = 0.0125 hrConverting to seconds, we have 0.0125*3600 = 45 secondsD. We have P(nk) = (λ/μ)[tex] ^k+1](/tpl/images/0435/2068/543bd.png)

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
