A pumping system is designed to pump from a storage reservoir located at an elevation of 1015 feet. The pump elevation is 1005 feet. The pump discharge flow rate is 4500 gal/min and the water temperature is 100˚ F. Between the storage tank and the pump is 30 feet of 14-in DIP pipe (f = 0.018) with one (1) rounded entrance (kent = 0.05), and two (2) 45 -degree bends (k45 = 0.30). What is the NPSHA for this system?...

A 30 cm well penetrates 45 m below the static water table. After a long period of pumping at a rate of 1200 lpm, the drawdown in the wells 20 m and 45 m from the pumped well is found to be 3.8 and 2.4 m respectively. Determine the transmissivity (=K*aquifer width) of the aquifer. What is the drawdown in the pumped well?

Two towns, located directly across from each other, operate municipal wastewater treatment plants situated along a river. The river flow is 50 million gal. per day (50 MGD). Coliform counts are used as a measure to determine a water%u2019s ability to transmit disease to humans. The coliform count in the river upstream of the two treatment plants is 3 coliforms/100 mL. Town 1 discharges 3 MGD of wastewater with a coliform count of 50 coliforms/100 mL, and town 2 discharges...

A 2,250 m3/day extended aeration system is used to treat sewage from Taman Maju Jaya. The average BOD influent of the sewage treatment plant is 250 mg/L and is reduced by 65% after the primary clarifier. It has two rectangular aeration tanks (working in parallel) with a dimension of 4 m width, 6 m length and 3.5 m water depth. The aeration tank maintains a biomass concentration of about 4000 mg/L. (i) Determine the food-to-microorganism ratio of the aeration tank...

A pump storage power plant in Tennessee produces electricity by allowing water from a reservoir to fall 100 meters at a flow rate of 1.02 m3/s through a 90% efficient turbine to generate electricity. Later a set of pumps send water back to the reservoir at the same flow rate but these pumps are only 80% efficient. The system runs for 300 days per year (150 days generating and 150 days pumping) and operates 22 hours per day generating then...

1. Two students are kayaking on the Saint John River. Initially, they are floating directly beside each other chatting and moving with the river current at 1.50 m/s downstream. Student A pushes away from Student B and sees Student B floating away from them at 1.00 m/s in the upstream direction. The combined inertia of Student A and their kayak is 100 kg and the combined inertia of Student B and their kayak is 120 kg. Assume that there is...
