    Graduate How can Bernoulli's theorem assume non-viscous fluid and critical velocity simultaneously?

    Thanks Guys.. :-)

    Graduate How can Bernoulli's theorem assume non-viscous fluid and critical velocity simultaneously?

    No. Its the velocity till which the flow of a perticular fluid is laminar.

    Graduate How can Bernoulli's theorem assume non-viscous fluid and critical velocity simultaneously?

    Two of the assumptions in Brenoulli's Theorem say 1. The fluid should be non-viscous 2. The velocity of fluid should be less than its critical velocity Now how can these two co-exist. We know that Vc = (N.n)/(D.p) Vc= Critical Velocity N= Raynolds No. n= viscosity coef. D= Dia of...

    Undergrad What is the primary cause of rolling resistance?

    In solids there are crests and troughs. In highly polished surfaces there are molecular forces. But what creates friction during rolling where there is only line contact (in case of cylinder) or point contact (inn case of a ring)? I read somewhere that when an object is rolling it forms a...
