    Abstract

    The hourly average wind speeds for 1958-1960 at Jodhpur in13; Rajasthan have been analysed to assess the wind power potentiality of Jodhpur. The frequency distribution of wind speeds, the average electrical energy extractable from wind by a generator of assumed characteristics and the quantity of water that can be pumped by a WP-2 type windmill have been determined. frequencies and duration of spells of low winds and the diurnal bahaviour of wind speed have also been discussed. quot;he The annual mean wind speed at Jodhpur is 9 km.p.h. The estimated annual energy output of a wind driven machine having a cut-in-speed of 8 km.p.h,, a swept area 30 sq.m. and an overall power coefficient of 12 per cent is 788 kWh. The average quantity of water that the W-2 type wind mill with an overall power coefficient of 12 per cent and swept area 23.6 sq,m, can pump is about 22,000 kiloliters a year or about 14,000 gals. per day.
