A 4,3 M DIAMETER WINDMILL WILL PUMP 7365 LITRES PER DAY AGAINST A TOTAL HEAD OF 81 METRES WHEN EQUIPPED WITH A 64 MM DIAMETER PUMP IF THE MEAN DAILY WINDSPEED IS 4 M/S.OTHER PUMPING AND WINDMILL CONFIGURATIONS ALSO APPLY. THE 7,5 METER SENESCHAL MILL CAN PUMP UP TO 216 METERS UNDER CERATIN LOADING CONFIGURATIONS. IF THE MEAN DAILY WINDSPEED IS 5 M/S THE DAILY DELIVERY WILL BE 5/4 TIMES THE TABULATED FIGURE.
