Abstract
The data of the hourly average wind speeds at Lucknow13; for the years 1958-'60 have been obtained from the India Meteorological Department. Based on these, the frequency distribution of wind speeds, estimated amount of energy extractable from wind and t h e estimated quantity of water that can be pumped by a windmill have been determined. The frequencies and duration of spells of low winds and the diurnal variation of wind speed have been examined.13; The annual mean wind speed at. Lucknow is 9 km.p.h.13; The estimated annual energy output of a wind driven machine13; having a cut- in speed of 8 hi.p.h., swept area 30 sq.m. and an overall power coefficient of 12 per cent is 1,320 kWh. The average amount of water that the off-2 type windmill with an overall power coefficient of 12 per cent and swept area of 23.6 sq.m. can pump i n a year i s about 40,000 kilolitres which works out to about 23,EOO gals. per day.
