Abstract : The control of water evaporation was studied at Jodhpur (Rajasthan) on aluminium pans and specially built concrete tanks with n-alkoxy ethanol, CH/sub 3(CH/sub 2)16 CH/sub 2 O. CH/sub 2 CH/sub 2 OH. Effect of different solvents was studied. Hydrocarbon solvents gave the best performance. Alcoholic solutions gave poor results. It was found that n-alkoxy ethanol always gave higher reduction in evaporation than cetyl alcohol or stearyl alcohol or their admixture, singly or combined with n-alkoxy ethanol in different proportions. The material heated upto 110 degree Celsius was stable and did not show any loss in its efficiency and performance. 25-35 per cent conservation of water can be obtained during summer and 50-60 per cent during winter. For the other periods the saving lies between these limits |

Abstract : Diurnal temperature profiles of Jodhpur soil in relation to depth on a few selected days of four different months have been presented. Thermal diffusivity of the soil has been estimated by three different methods and the values, obtained by one of these methods, have been utilized for evaluating the depth of penetration of diurnal temperature wave, which is found to be 50.1 cm on the average. Certain other aspects of surface temperature in relation to ambient temperature, have been discussed. |
