Consider that water is pumped a distance equal to the last three digits of 917551848 in kilometer from a reservoir (Reservoir A) at mean sea level elevation to a second reservoir (Reservoir B) at elevation 50 ft. above mean sea level. The pipeline connecting the reservoirs has a diameter of 60 in and is constructed of concrete with an absolute roughness of 0.003. If the flow is equal to 917551848 in liter per week and the efficiency of the pumping station is 75%, what will be the monthly power bill if electricity costs is the same as the highest rate of the electricity provider of your community in cents/kwh?

- A dam supplies to a suburban area using a 0.21m diameter pipeline that is 881m long. For the water to reach the intended reservoir, a pump is needed to raise the flow to a point 121m above the pump. If the flow within the pipe is 0.11 m3/s, determine the savings in horsepower if the engineers decided to replace the old pipe (f = 0.033 with a new 0.28m diameter pipe with f = 0.022.arrow_forward(A)Describe what is Cavitation in pumps and how it can be avoided?(b).

The population is estimated to increase to 940 by the year 2035. The average peak flow is currently 1.2 L/sec and is expected to increase to 2.14 L/sec by 2035. The organic load is estimated to be 45 gram BOD5/capita-day. The community is considering a free surface wetland to treat their wastewater. (a) What is the BOD5 loading generated in the year 2035 (kg/day)? (b) Use the BOD loading to estimate the maximum surface area (ha) required for a free surface wetland that would serve the community in 2035 and remove BOD to 30 mg/L. (c) Assuming you are now considering sizing a facultative lagoon instead of a free surface wetland. Quickly estimate the required surface area (m2) for a facultative lagoon to handle a peak flow in 2035, assuming a design water depth of 4 m and a hydraulic detention time of 20 days.arrow_forward
