  • Low specific speed centrifugal pumps have low flow rates and high heads. They are widely applied in the petroleum, chemical, aerospace, pharmaceuticals, metallurgy, and light industries, among others. With the development of space technology and petrol chemical industry, the highly stable cavitation performance of centrifugal pumps has been put forward. Poor cavitation performance is one of the key problems in low specific speed centrifugal pumps.

  • I. Introduction An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.

  • SERVICE PROCESS KAIZEN: ADOPTING PROCESS STABILIZATION METHODS TO CONTROL SERVICE WORK FLOW AND TO IMPROVE CUSTOMER SERVICE I drop MSAs that are not in SAT states or where available completion rate data cover less than two thirds of public enrollment. This leaves a sample of 931 districts from 50 MSAs. In spite of the serious limitations in the CCD data, the pattern of results in Panel D is quite similar to that in Panel C. Again, the student quality index is a strong predictor of completion rates, but its coefficient is (insignificantly) smaller in high-choice than in low-choice MSAs....

  • Linking up with Chapter 2, dealing with uniform flow in open channels, it may be noted that any change in the flow phenomenon (i.e. flow rate, velocity, flow depth, flow area, bed slope do not remain constant) causes the flow to be non-uniform. This chapter will discuss the effect of change in any one of the above quantities, including specific energy, critical depth and slope, and flow types. How to draw water surface profiles will also be introduced.

  • .This page intentionally left blank .Capital Budgeting This book explains the financial appraisal of capital budgeting projects. The coverage extends from the development of basic concepts, principles and techniques to the application of them in increasingly complex and real-world situations. Identification and estimation (including forecasting) of cash flows, project appraisal formulae and the application of net present value (NPV), internal rate of return (IRR) and other project evaluation criteria are illustrated with a variety of calculation examples.

  • Banks operating in the main developed countries have been exposed, since the Seventies, to four significant drivers of change, mutually interconnected and mutually reinforcing. The first one is a stronger integration among national financial markets (such as stock markets and markets for interest rates and FX rates) which made it easier, for economic shocks, to spread across national boundaries.
