In the design of a city water supply system, three reservoirs are connected by three pipes which meet at the junction. Reservoir A needs to supply 0.0938 m3/s to lower reservoirs B (Elevation 150 m) and C (Elevation 140 m). Pipe 1 is 900 m long and 300 mm in diameter, pipe 2 is a 200 mm diameter pipe 387 m long, and pipe 3 is 200 mm in diameter and 700 m long. The roughness coefficient for all pipes is 0.011.
a. Determine the discharge in pipe 2.
b. Compute the discharge in pipe 3.
c. What is the elevation of the water surface of reservoir A?

A city plans to upgrade its storm water management infrastructure by installing new pipes. The installation costs 2.1 million dollars and the annual maintenance cost is $28,000. Every 10 years, the system needs to be fully examined which requires a fixed management and material cost of $ 20,000 and a variable labor cost at the rate of $25/hr. 8 full time (working 8 hours per day) workers will be employed for 40 days for this task. If the infrastructure has...

A system of caves is a group of connected underground tunnels. Design an ADT for a cave and a cave system. An archaeologist should be able to add a newly discovered cave to a cave system. He/she can enter this system through only one cave and exit the system only through a different cave. Duplicate caves – based on GPS coordinates – are not permitted. Archaeologists should also be able to list the caves in a given cave system. (JAVA)

Thirty-two 1-Liter specimens of water were drawn from the water supply for a city and the concentration of lead in the specimen was measured. The average level of lead was 7.3 µg/Liter, and the standard deviation for the sample was 3.1 µg/Liter. Using a significance level of 0.05, do we have evidence the mean concentration of lead in the city’s water supply is less than 10 µg/Liter? Find: The t critical value ? If the true mean equals the null...
