A turbine operates on superheated steam that enters at 80 bar absolute and 500˚C, and leaves the turbine at 7.5 bar absolute and

250˚C. The flow rate of the steam is 400 kg/min and the turbine operates adiabatically. The steam exiting the turbine goes to a heater, which is supplied with 2000
2kW of energy. The steam leaves the heater at 5 bar absolute. All of the pipes through which the

steam flows are 0.5 m (id) in diameter.

a. How much power is produced by the turbine? (4 marks)

b. What is the temperature of the steam leaving the heater? (4 marks)

c. What is the velocity (m/s) of the steam entering the turbine? (3 marks)

d. To what temperature can the steam at 80 bar be cooled before a liquid will appear?

Based on these ideas, what are the pro's and con's for both Sexual Reproduction and Asexual reproduction?
Svetradugi [14.3K]
Asexual
Pro:
1. inexpensive to make offspring (usually make a lot at a time and not invest a lot of time in raising them).
2. Do not need a mate to reproduce.
3. Can rapidly expand a population
Con:
1. genetically identical- prone to extinction because once a parasite has evolved to attack a specific genotype, it can kill them all.
2. Lineages usually don't last longer than a couple thousand years

Sexual:
Pros:
1. Genetically unique- so more likely to create a "successful" offspring
2. Lineages more likely to last hundreds of thousands of years

Cons:
1. More effort into creating offspring- require more parental effort
2. STD's- easily to pass
3. need to find a mate or else won't be successful as an organism.

Hope this helps you.
