The curve of flow-head is one of the most important indicators to assess water pump performance. While it is difficult to get measured data in real condition and the data is very limited. The method of pump data mining based on support vector machine (SVM) is built due to its superiority in dealing with small sample event. The method is aimed at finding out the unknown data between measured data and drawing more accurate flow-head curve. It was found that the model of pump data mining based on SVM is much better than neural network when their curves are compared.

Three methods of evaluating beef sires for weaning weight with data obtained from an organized young sire progeny testing program were compared. Information from Agriculture Canada’s National Beef Sire Monitoring Program was utilized along with computational procedures based on best linear unbiased prediction. The methods were applied to data from the Canadian Simmental Association as an illustration of the methods. A model which incorporates the proofs of the reference sires into the comparisons with test bulls was considered more appropriate than the other two models compared. The results also showed that even in an organized progeny test program, test bulls are not truly mated to cows of equal merit or across equal herd environments.

Design And Manufacture

In this study, the flow rate, velocity, head, and power in a designed and manufactured centrifugal water pump were studied and determined experimentally. The effect of the impeller with different blades on the centrifugal pump performance has been investigated. Three different impellers with 4, 5, and 6 blades are tested to determine the number of the optimum blades. The experimental results showed that the flow rate, velocity, heat, and power are higher for the case of the impeller with 6 blades than that for the two cases of 4 and 5 blades. The losses decrease by increasing the number of the blades due to the reduction of the secondary flow for a certain limit. The experimental results showed better centrifugal water pump performance when an impeller with 6 blades is used.
