flow ratetemperatureSwell and sag drawdown significantly influence the high density polyethylene parison. Numerical simulations of the flow field of a HDPE melt were performed using the finite element method for the die of plastic pipe extrusion and parison formation. The constitutive equation of ...
8、3.4-11 ) for Rm in equation (3.4-9 ) gives,Equation (3.4-12) relates the flow rate of filtrate to the pressure drop,3.4-12,The thickness of cake deposited and other parameters, some of which can , in certain circumstances, be assumed to be constant.,1. Pressure drop The pressure...
aIn this equation, q is the turbine flow rate; p0 represents the static pressure of the water column, p the pressure at the turbine admission and pf the pressure loss due to friction in the conduit. Tw is a characteristic constant of the conduit which is usually known as the water time ...
Here we present the calculations of incoherent current flowing through the two-site molecular device as well as the DNA-based junction within the rate-equation approach. Selected phenomena of interest are discussed in detail. The structural asymmetry of a two-site molecule results in a rectification...
The gas mass flow rate and temperature can be controlled independently of the energy input, by proper selection of the plasma system. In combustion systems, the gas flow rate, temperature, and energy input are independent. View article Wellbore performance Boyun Guo, in Well Productivity Handbook ...

The rate of heat flow in a rod of material is proportional to the cross-sectional area of the rod and to the temperature difference between the ends and inversely proportional to the length. Heat flow = - (heat transfer coefficient) * (area of the body) * (variation of the tem-peratur...
Optimal scheduling strategy of integrated energy systems (IES) with combined cooling, heating and power (CCHP) has become increasingly important. In order to make the scheduling strategy fit to the practical implementation, this paper proposes a variable performance parameters temperature–flowrate schedul...
The heating, ventilation, and air conditioning (HVAC) systems significantly influence the operating room environment, including temperature, relative humidity, pressurization, particle counts, filtration, and ventilation rate. A full-scale operating room has been investigated extensively through field ...
The operating conditions are also essential for flow batteries performance, such as the temperature and flow rate [25,26]. Ma et al. [25] found that with increasing flow rate, the capacity of the battery increases, but the system efficiency decreases and strategies were applied to optimize ...
