Force, Momentum Change, and Motion 来自 AIP Publishing 喜欢 0 阅读量: 36 作者:Tiersten,S Martin 摘要: Classical equations of motion for open systems are discussed and the equation of motion for fixed volume systems is shown to be F = +Φ, where Φ is the momentum flux. Numerous examples...
This is the crucial contribution to ∇ * (ρv); the other two contributions vanish in this example. We have a net outflow of fluid, which causes a decrease in the density of the fluid in the control volume, in accordance with equation 5.John Denker...
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 ...
When the momentum equation is used to calculate the resultant force of the fluid on the object, the pressure at the inlet and outlet should be ( ) A absolute pressure B gage pressure C Atmospheric pressure D vacuum pressure 相关知识点: ...
Compute the time required for a force of 1500 N to bring the car to rest. The mass of Earth is 5.972 × 1024 kg and its orbital radius is an average of 1.496 × 1011 m. Calculate its linear momentum.Glossarylinear momentum: the product of mass and velocity...

The Rate of change of momentum of a body is equal to the resultant force acting on the body, and takes place in the direction of the force.To determine the rate of change of momentum for a fluid we will consider a streamtube as we did for the Bernoulli equation,We start by assuming ...
Force (F) measured in newtons, time (t) measured in seconds, velocity (v) measured in in m/s and mass (m) in kilograms. When we divide both sides by Δt we get an equation for force. Equation 1. When the denominator in a fraction gets larger while the numerator remains constant, ...
