Trace a State Space Tree introduced in the Chapter 5.1 using algorithms depth_first_search (page 205), checknode (page 207), and expand (page 210).
Assume that State Space Tree is a two-level full binary tree (root is level 0). Node #2 (according to notation used in the Figure 5.1, page 204) is non-promising.
Count the number of steps performed by each of those three algorithms. Consider execution of instructions like "visit node" or execution of "promising function" as one step, "write a solution" as an exit call.
Note: no need to print or a draw a whole tree. Just provide three numbers as an answer
2- An inlet water solution of 100 kg/h containing 0.010 wt fraction nicotine (A) in water is
stripped with a kerosene stream of 200 kg/h containing 0.0005 wt fraction nicotine in a
countercurrent-stage tower. The water and kerosene are essentially immiscible in each other. It is
desired to reduce the concentration of the exit water to 0.0010 wt fraction nicotine. Determine the
theoretical number of stages needed. The equilibrium data are as follows, with x the weight
fraction of nicotine in the water solution and y in the kerosene:

- A commercial office building is located in the city of Lansing, Michigan, and is heatedusing a gaseous fuel with a heating value of 725 Btu/std ft3. The indoor designtemperature is 71ºF. The heat load for the building is known to be 250,000 Btu/hr. Thisheat load accounts for the fact that there are internal heat gains in the building, due tothe presence of people and electronic equipment (e.g., lights and radios). People in thebuilding are usually seated and involved in light activity.a) The furnace had an initial efficiency factor of 73% when installed, but since thenefficiency-improvement retrofits were implemented that raised the efficiency factorto its present value of 82%.
