Parts arrive at a two-machine system according to an exponential interarrival distribution with mean 20 minutes; the fi rst arrival is at time 0. upon arrival, the parts are sent to machine 1 and processed. the processing-time distribution is tria(4.5, 9.3, 11) minutes. the parts are then processed at machine 2 with a processing-time distribution as tria(16.4, 19.1, 20.8) minutes. the parts from machine 2 are directed back to machine 1 to be processed a second time (same processing-time distribution as the fi rst visit but an independent draw from it). the completed parts then exit the system. run the simulation for a single replication of 20,000 minutes to observe the average number in the machine queues and the average part cycle time.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
