Question

A pump with an efficiency of 80%80\% is used to draw groundwater from a well for irrigating a flat field of area 108 hectares108\text{ hectares}. The base period and delta for paddy crop on this field are 120 days120\text{ days} and 144 cm144\text{ cm}, respectively. Water application efficiency in the field is 80%80\%. The lowest level of water in the well is 10 m10\text{ m} below the ground. The minimum required horse power (h.p.) of the pump is ________. (round off to two decimal places)
(Consider 1 h.p.=746 W1\text{ h.p.} = 746\text{ W}; unit weight of water = 9810 N/m39810\text{ N}/\text{m}^3)
