When actuated, a synthetic jet delivers positive momentum but no net mass flow per cycle.
Baking of the vacuum vessel up to 110 °C with ±10 °C deviation was achieved with a net mass flow rate of 0.8 kg/s at 1.5 bar gauge inlet pressure and supply temperature of 230 °C at the heater end.
Net mass flow toward the shell occurs because Ag diffuses faster into Au than vice versa.
The mass conservation equation for a CV states that the time-rate of change of mass within the CV must equal the net mass flow into the CV through the control surface (CS) plus the net production (production minus absorption) of mass within the CV.
The results of optimization showed that the highest net power output, mass flow rate of natural gas delivered to city and the flue gas temperature discharged to the environment are obtained for the exergy efficiency optimal design.
Many mass balances conducted for fluorochemicals showed a net increase of mass flow during wastewater treatment, thereby resulting in overall positive mass balances.
Topics include Darcy equation, flow nets, mass conservation, the aquifer flow equation, heterogeneity and anisotropy, storage properties, regional circulation, unsaturated flow, recharge, stream-aquifer interaction, well hydraulics, flow through fractured rock, numerical models, groundwater quality, contaminant transport processes, dispersion, decay, and adsorption.
If for 1 MW net power output, both of the mass flow rates of CO2 and NH3 are 7.4 kg/s with LNG mass flow rate of 14.8 kg/s.
It is shown that within a wide range of temperatures the deviation in net power output between the simpler mass flow method and the more sophisticated combined method is below 10%.
A regenerative organic Rankine cycle (RORC) system is designed to recover the exhaust heat of a diesel engine, and the influence of the intermediate pressure (the pressures at which the steam is extracted from the expander) on performance parameters such as net power output, thermal efficiency and mass flow rate of the working fluid are analyzed.
The effects of expander inlet pressure and temperature on net power output, thermal efficiency, total cost, mass flow rate, and available efficiency of the WHR system are analyzed.
