mean water temperature downstream from a discharge pipe at a power plant cooling tower should be no more than 100°F. Past studies has shown that the standard deviation of temperature is 2°F. The water temperature was measured on 10 randomly chosen days, and the results are shown below: 96.15 , 97.81 , 97.09 , 95.0P , 99.46 , 100.03 , 99.74 , 98.85 , 95.08 , 98.71

a. State the null hypothesis and alternative hypothesis for the above problem.

b. Is there evidence that the water temperature is acceptable at α = 1%?

c. Compute the 95% confidence interval for the mean temperature of water.

The mean water temperature downstream from a power plant cooling tower discharge pipe should be no more than 97oF. Past experience has indicated that the standard deviation of temperature is 2oF. The water temperature is measured on 4 randomly chosen days, and the average temperature is found to be 94oF. Conduct a hypothesis testing using the 7 steps at a 5% significance level.

Consider a 400-MW, 32 percent efficient coal-fired power plant that uses cooling water withdrawn from a nearby river (with an upstream flow of 10-m3/s and temperature 20 °C) to take care of waste heat. The heat content of the coal is 8,000 Btu/lb, the carbon content is 60% by mass, and the sulfur content is 2% by mass. How much electricity (in kWh/yr) would the plant produce each year? How many pounds per hour of coal would need to be...

A water tower supplies water to a city through a pipe with 1 ft diameter. The pipe is 0.5 miles long and is made of commercial steel pipe. Over the years, the supply line lost head and engineers are considering the replacement of 94 percent of the pipe length with a larger diameter pipe (same type). The peak water demand is 3.53 ft3/sec. How much pressure head could be gained by this strategy?

A wastewater plant needs to reduce the methane content in water in a stripping tower to 0.3 mol %. The liquid stream is entering the tower with a flow rate of 200 mole/h and contains 0.8 mol % methane. The tower uses pure air for stripping and its temperature and pressure are held constant at 300 K and 1 atm, respectively. The equilibrium relation for methane in the air-water system is ? = 1.2?. a) Find the minimum vapor flow...
