Tricks for Froude number, mach number, weber number, reynolds number, Euler's number cauchy number

 Tricks for  Froude number, mach number, weber number, reynolds number, Euler's number cauchy number

Froude number- yadi ham ise Hindi uchcharan main kuchh is tarh pade ki frud,  to ham payenge ki ismain chhote उ ki maatra aa rahi hai or isi yarah gurutva main bhi chhote उ ki maatra aa rahi hai. To dimag ki ghanti baji.... 

Froude number is equal to  inertia force divide by gravity force or jadatva bal batte gurutva bal.

Note- under root of inertia force divided by gravity force.

Weber number- बेवड़ा daru pee ke tention leta hai. Its mean weber number is the ratio of inertia force to tension force.

Note- uder root of inertia force divided by tension force.

Mach number- just imaging you draw a wire of bow to through a arrow at mach speed. After left to through arrow the wire back into old state. This concept accepted to elastic theory. Then you realise that mach number is equal to ratio of under root of inertia force to elastic force.

Mach number = √inertia force/√ elastic force

Euler number- Euler will just say as boiler. Boiler main pressure hota hai.

Euler number=√inertia                                                                force/√pressure force

Reynolds number- Reynolds went to disco. Here disco' s rhyming word as visco. Then visco introduce to viscosity. So, Reynolds number is the ratio of inertia force and viscous force.

Reynolds number=inertia force/viscous force

Cauchy number- if you play with marble in your childhood in india. Just imaging cauchy to caunchy.

Trick- plastic Ka kancha

You can imagin Plastic as elastic and kancha as caunchy.

Cauchy number = inertia force/elastic force

Note - don't confuse between cauchy number and mach number. The main difference between them under root or without under root.
