искомый

•

We now have the desired result.

•

We can then calculate the required partial derivatives directly.

•

The solution sought is given by ...

•

This is the final form of the sought-for equation.

Искомый (коэффициент)-- Equation (...) can be regarded as defining a friction head loss coefficient of interest. Искомый -- desired, required (в пре- и постпозиции); sought (в постпозиции); of interest

 For any combination of j and q a value of n may be calculated to give the desired d parameter.

 Initial analyses of the configuration desired were done neglecting the effects of friction.
