force is $5\mathrm{.}50$ N $.$ Estimate the drag force on the prototype submarine at the given conditions.

For water at $T=15C$ and atmospheric pressure, $=999\mathrm{.}1k\frac{g}{m^3}$ and $=1\mathrm{.}138{10}^{-3}k\frac{g}{m}*s.$

For air at $T=25C$ and atmospheric pressure, $=1\mathrm{.}184k\frac{g}{m^3}$ and $=1\mathrm{.}849{10}^{-5}k\frac{g}{m}*s.$

The drag force on the prototype submarine is estimated to be $$ N$.$
