Hints : (a) as a first step, i would recommend implementing your own ver- sion of hash sets, called "myhashset". i would suggest using the mylinkedlist class from the last assignment as an example. i. your hash set should support an "add" method, which takes in a string and puts it in the set. ii. your hash set should support a "contains" method, which takes in a string and returns true if it’s in the set, and false otherwise. iii. your hash set should contain an array for holding the underlying data. iv. your hash set should include a hash function. i suggest research- ing one on the internet and using that.

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

Precipitation hardening can be achieved in many light alloys by a three-step heat treatment. what is carried out and what is the purpose at each step? why is such a treatment necessary based on the nucleation and growth theory of phase transformation. compare this treatment with tempering martensite for carbon steels (similarities and differences).
