百度试题 结果1 题目 In the momentum equation, for steady flow the net force on the fluid mass is equal to the net rate of outflow of momentum across the control surface. ()A.对B.错 相关知识点: 试题来源: 解析 A 反馈 收藏 ...
The magnitude of the frictional force is often directly proportional to the normal force, or the force pressing the two surfaces against each other. The constant of proportionality varies depending on the surfaces which are in contact. For example, you might expect smaller friction when two "slick...
In particular, we find the conditions for which both treatments provide the same forces. The presented investigations are performed by analogy to the schemes and ideas proposed in Ref. 1.doi:10.1142/S021773231350154XDaszkiewicz, MarcinWorld Scientific Publishing CompanyModern Physics Letters A...
When a linear force causes rotation, the resulting motion is perpendicular to both the force and the object, and theis the cross product of the lever arm and the applied force,τ→=r→×F→whereτ→stands for torque,r→is the lever arm, andF→is the force. It is possible to define ...
. The latter process is reversible because only a slight increase in the restraining force could reverse the direction of the process from expansion to compression. For reversible processes the system is inequilibriumwith itsenvironment, while for irreversible processes it is not....
This spherical shape has the lowest surface area for a specified volume of liquid. Sign in to download full-size image Fig. 3. The net force on the bulk molecules is zero and on the surface molecules is not zero [27]. In addition to surface tension, some external forces such as ...
By assuming the value of a to be 0.3 (this is an estimate of the net specific growth rate of the prey in the absence of the predator), the complete set of constants is: α=0.3β=0.0130γ=0.2106δ=0.0002015 These initial conditions are taken from Allen [10] for 1959, the earliest ...
Calculate the x and y components of the net pressure force on the cell (per unit depth). Q3. (MSc Examination, April 2005) (a) Explain (briefly) how an equation for pressure is derived in finite-volume calculations of incompressible fluid flow. (b) Explain how the problem of "odd-even...
To conclude with the SOM construction, we force a clustering (or coarse-graining) in the reduced SOM space49, using the procedure illustrated in Fig. 12. For this purpose, we use a hierarchical clustering of the (Tanimoto) distances among the unit codebooks in the diagnostic horizons layer ...
