Consider a queueing system in which the mean arrival rate is 800 veh/h and mean service rate is 1200 veh/h. Draw a graph showing the effect of intensity on queue length characteristics [namely L, Lq, E(m/m>0), and Var(n)] (i) When the queue system is an M/M/1, (ii) when the queue system is an M/D/1
Comment on the graphs and how they relate

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Determine the damped natural frequencies and the steady state response of a decoupled damped forced two degrees of freedom system. 10ä1 + 2q1 20q1 10 cos t; 10q2 +4q2 + 40q2 10 cos t

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
