The chapter also discusses problems on the calculation of total discharge head (TDH) in different situations. Furthermore, the chapter discusses affinity formulas to define relationships among impeller diameter, pump head, and brake horsepower (BHP)....
Mathematical modelling and preliminary calculation of the thermal parameters of the process were carried out. The results of the full-scale experiment confirmed the correctness of the theoretical assumptions made and the high efficiency of the developed MHD circulation melting circuit.Data...
and easy-to-use calculation formulas. This imperative arises in the context of local-level decision-making processes. While current methods address national or European-scale analyses, as well as the planning of individual buildings or district heating grid configurations, a fundamental question persists...
Due to the lack of understanding in the flow mechanism of the hub plate crown, the current calculation of the disc friction loss and the axial thrust in the centrifugal pump often uses empirical formulas. Research on the flow characteristics of the hub plate crown is of practical significance....
The calculation of the nonenergy costs follows some known conditions. (1) The lifetime of the equipment in the system is 20 years; the salvage value of the heat pump units, pumps, and other equipment (SV1) accounts for 10% of the initial investment in the system; and the salvage ...
