1)Describe TWO differences between viscous and inviscid flows in Balance Law of Linear Momentum.

Expert Solution

The two differences in viscous and inviscid flow iin balanced law of linear momentum are ;

1. In visous flow as we know that that there is viscous force acting between the two successive layers in opposite direction to the , the velocity of will be different acroos diffrent layers. But in inviscid flow as there is no force acting between two layers opposite to the direction of motion so the velocity will dame for all the layers.

For Viscous = u= velocity, y= vertical distance;

For inviscous = ( no shear force bcz no viscosity) ,

2. Since there is a viscous force acting opposite to the motion of fluid in viscous flow , so there is a loss of momentum in viscous flow and hence for energy is required to mantain the flow of fluid. Where as in inviscid flow such opposing force is missing , no loss of momentum occurs , so no energy is required to keep the motion continue.
