A 40 cm diameter well has been constructed in a water-table aquifer. A pump capable of continuous discharge at 600 m3/day has been installed to test the well. Observation wells are located 10 meter and 50 meters from the pumped well. After pumping continuously for 36 hours the drawdowns were 3.6 meters and 1.20 meters respectively. At this time the drawdown in the pumping well was 8 meters. Determine the entrance losses, if any, after 36 hours of pumping.
