Centrifugal Pump Operation and Solutions of problems
If a centrifugal pump is cavitating several changes in the system design or operation may be necessary to increase the NPSHA above the NPSHR and stop the cavitation One method for increasing the NPSHA is to increase the pressure at the suction of the pump For example if a pump is taking suction from an enclosed tank either raising the level of the liquid in the tank or increasing the

Analyzing Air Handling Unit Efficiency
Several heat pumps were instrumented with four-channel loggers placed in the ceiling plenum near the unit A temperature probe was directed through the ceiling and toward the heat pump's thermostat for space temperature monitoring One probe was placed in the discharge air side of the heat pump and one in the rear of the heat pump where duct
Application of TOUGHREACT to performance evaluations
Numerical simulations were performed with a non-isothermal multi-phase reactive geochemical transport code TOUGHREACT for predicting changes in temperature permeability porosity and injectivity resulting from a long term operation of a geothermal heat-pump (GHP) system A one-dimensional model was developed to simulate a GHP system for a potential geothermal reservoir with down-hole water
