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.
