Deduce the formula of Reynolds number in the form of inertial force and viscous force . |
|
Answer» Solution :REYNOLDS number `R_(e)=(rhov^(2))/(((etav)/d))` Multiplying and DIVIDING by A to right side equation, `R_(e)=(rhoAv^(2))/(((etaAv)/(d)))` `R_(e) = ("INERTIAL force")/("Viscous force")` Thus `(R_(e)`represets the ratio of inertial force, that is force due to mass of moving fluid or due to inertia of obstable in its path to viscous force) HENCE`R_(e)` represents the ratio of inertial force of to viscous force. |
