Entomopathogenic nematodes (EPNs) are parasites of insects. EPNs are currently used as biopesticides for controlling several important insect pest worlds wide. EPNs are extraordinarily lethal to many important soil insect pests, yet are safe for plant and animals. This high degree of safety means that unlike chemicals or even Bacillus thuringiensis, nematode application do not require masks or other safety equipments. Biological control of insect pests using EPNs has gained importance in the recent year. Because they are highly virulent, killing their host within 24 to 48 hrs. They can be...

In this book the CFD analysis of a centrifugal pump is done using k-ε turbulent modeling and SIMPLEC algorithm from which the velocity and pressure contours are plotted for different operating conditions. In this work the mass flow rate is varied three times for two different fluids that are water and fuel oil. First the mass flow rate is decreased by 10% from the initial value of mass flow rate and then increased by 10% from the initial value of mass flow rate. Using the results of varying mass flow rate the efficiency at different mass flow rate is calculated. The results are compared...
