You have been asked to evaluate the economic implications of
various methods for cooling condenser effluents from a 200-MW
steamelectric plant. There are two basic types of cooling towers:
wet and dry. Furthermore, heat may be removed from condenser water
by (1) forcing(mechanically) air through the tower or (2)
allowing heat transfer to occur by making use of natural draft.
Consequently, there are four basic cooling tower designs that could
be considered. Assuming that the cost of capital to the utility
company is 12% per year, your job is to recommend the best
alternative (i.e., the least expensive during the service life).
Further, assume that each alternative is capable of satisfactorily
removing waste heat from the condensers of a 200-MW power plant.
What noneconomic factors can you identify that might also play a
role in the decision-making process?

You have been asked to evaluate 2 pollution control devices. The wet scrub costs $100 to set up and $50 per year to operate. It must be completely replaced every 3 years, and it has no salvage value. The dry scrub device costs $200 to set up and $30 per year to operate. It lasts for 5 years and has no salvage value. Which control device you recommend if the cost of capital is 10%? Select one: a. Dry scrub,...

H1- COOLING TOWER [10 p] 1. What is the wet bulb temperature? How can you measure it? Is the wet-bulb temperature greater than dry-bulb temperature? Why? [10 p] 2. A cooling tower is to be designed to cool 8 kg/s of water from 37°C to 29 °C. Entering air is 25 °C and at 30 % relative humidity. Leaving air is 22 °C and at 90% relative humidity. a) Calculate the air flow rate, G. b) Determine the possible lowest...

A small coastal town in Queensland is subject to an increasing permanent population and also a transient influx of tourists during the summer period. Council already receives frequent complaints of restricted water supply. The water supply system comprises a rising trunk main from the treatment plant A to the service reservoir B, the service reservoir, and service mains to the consumption areas. Two consumption areas C and D at different elevations are gravity supplied from the service reservoir. The service...
