From a deep well, water is being pump through a 250mm pipe, 400m long into an elevated tank. If the tank operates continuously, the water in the well draws down to elevation 25m. The pressure gage reads 450kPa and assume friction factor f = 0.02. Compute the pump discharge and the total head provided by the pump neglecting minor losses. Using a pump efficiency of 70%, solve for the monthly cost of pumping if the average pumping time is 6 hours per day and electric energy costs P1.75 per kilowatt hour.

Two pipes 1 and 2 are connected in series. Pipe 1 is 200 mm in diameter and 300 m long while pipe 2 is 250 mm in diameter and 200 m long. Determine the total head loss of the pipes in series neglecting minor losses if the discharge is 128 liters per second. Use f=0.02 for all pipes.
An engineer is hired to design a swimming pool 15 m long by 6 m wide by 2 m deep. For water supply, he decides to lay 600 m of 5 cm pipe with f = 0.020 from a nearby main to the pool. The pipe will discharge freely into the pool during the entire filling process. The average pressure at the water main is 550 kPa and the difference in elevation between the two ends of the pipe is 10 m, with the discharge end higher than the intake end. Assuming that 10 % of the loss in the pipeline are due to transitions, fittings, and valves, how long will it take to fill the swimming pool?
